Tags Share this article 5/3/22 Published Prof. Avishai Wool, AlgoSec co-founder and CTO, breaks down the truths and myths about micro-segmentation and how organizations can better secure their network before their next cyberattack Network segmentation isn’t a new concept. For years it’s been the go-to recommendation for CISOs and other security leaders as a means of securing expansive networks and breaking large attack surface areas down into more manageable chunks. Just as we separate areas of a ship with secure doors to prevent flooding in the event of a hull breach, network segmentation allows us to seal off areas of our network to prevent breaches such as ransomware attacks, which tend to self-propagate and spread laterally from machine to machine. Network segmentation tends to work best in controlling north-south traffic in an organization. Its main purpose is to segregate and protect key company data and limit lateral movement by attackers across the network. Micro-segmentation takes this one step further and offers more granular control to help contain lateral east-west movement. It is a technique designed to create secure zones in networks, allowing companies to isolate workloads from one another and introduce tight controls over internal access to sensitive data. Put simply, if network segmentation makes up the floors, ceilings and protective outer hull, micro-segmentation makes up the steel doors and corridors that allow or restrict access to individual areas of the ship. Both methods can be used in combination to fortify cybersecurity posture and reduce risk vulnerability across the security network. How does micro-segmentation help defend against ransomware? The number of ransomware attacks on corporate networks seems to reach record levels with each passing year. Ransomware has become so appealing to cybercriminals that it’s given way to a whole Ransomware-as-a-Service (RaaS) sub-industry, plying would-be attackers with the tools to orchestrate their own attacks. When deploying micro-segmentation across your security network, you can contain ransomware at the onset of an attack. When a breach occurs and malware takes over a machine on a given network, the policy embedded in the micro-segmented network should block the malware’s ability to propagate to an adjacent micro-segment, which in turn can protect businesses from a system-wide shutdown and save them a great financial loss. What does Zero Trust have to do with micro-segmentation? Zero trust is a manifestation of the principle of “least privilege” security credentialing. It is a mindset that guides security teams to not assume that people, or machines, are to be trusted by default. From a network perspective, zero-trust implies that “internal” networks should not be assumed to be more trustworthy than “external” networks – quotation marks are intentional. Therefore, micro-segmentation is the way to achieve zero trust at the network level: by deploying restrictive filtering policy inside the internal network to control east-west traffic. Just as individuals in an organization should only be granted access to data on a need-to-know basis, traffic should only be allowed to travel from one area of the business to another only if the supporting applications require access to those areas. Can a business using a public cloud solution still use micro-segmentation? Prior to the advent of micro-segmentation, it was very difficult to segment networks into zones and sub-zones because it required the physical deployment of equipment. Routing had to be changed, firewalls had to be locally installed, and the segmentation process would have to be carefully monitored and managed by a team of individuals. Fortunately for SecOps teams, this is no longer the case, thanks to the rapid adoption of cloud technology. There seems to be a misconception associated with micro-segmentation where it might be thought of as a strictly private cloud environment network security solution, whereas in reality, micro-segmentation can be deployed in a hybrid cloud environment – public cloud, private cloud and on-premise. In fact, all public cloud networks, including those offered by the likes of Azure and AWS, offer “baked in” filtering capabilities that make controlling traffic much easier. This lends itself well to the concept of micro-segmentation, so even those businesses that use a hybrid cloud setup can still benefit enormously. The Bottom Line Micro-segmentation presents a viable and scalable solution to tighten network security policies, despite its inherent implementation challenges. While many businesses may find it hard to manage this new method of security, it’s nevertheless a worthwhile endeavor. By utilizing a micro-segmentation method as part of its network security strategy, an organization can immediately bolster its network security against possible hackers and potential data breaches.

Cloud Security Don’t Neglect Runtime Container Security Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 9/21/20 Published The Web application and service business loves containers, but they present a security challenge. Prevasio has the skills and experience to meet the challenge. Its runtime scanning technology and techniques will let you avoid the serious risks of vulnerable or compromised containers. The very thing that makes Docker containers convenient — their all-in-one, self-contained structure — makes them opaque to traditional security tests. Instances come and go as needed, sometimes deleting themselves within seconds. This scalable and transient nature isn’t amenable to the usual tools. Prevasio’s approach is specifically designed to analyze and test containers safely, finding any problems before they turn into security incidents. The container supply chain Container images put together code from many sources. They include original source or binary code, application libraries,language support, and configuration data. The developer puts them all together and delivers the resulting image. A complex container has a long supply chain,and many things can go wrong. Each item in the image could carry a risk. The container developer could use buggy or outdated components, or it could use them improperly. The files it imports could be compromised. A Docker image isn’t a straightforward collection of files, like a gzip file. An image may be derived from another image. Extracting all its files and parameters is possible but not straightforward. Vulnerabilities and malicious actions We can divide container risks into two categories: vulnerabilities and malicious code. Vulnerabilities A vulnerability unintentionally introduces risk. An outsider can exploit them to steal information or inflict damage. In a container, they can result from poor-quality or outdated components. The building process for a complex image is hard to keep up to date. There are many ways for something to go wrong. Vulnerability scanners don’t generally work on container images. They can’t find all the components. It’s necessary to check an active container to get adequate insight. This is risky if it’s done in a production environment. Container vulnerabilities include configuration weaknesses as well as problems in code. An image that uses a weak password or unnecessarily exposes administrative functions is open to attacks. Malicious code Malware in a container is more dangerous than vulnerabilities. It could intrude at any point in the supply chain. The developer might receive a compromised version of a runtime library. A few unscrupulous developers put backdoors into code that they ship. Sometimes they add backdoors for testing purposes and forget to remove them from the finished product. The only way to catch malware in a container is by its behavior. Monitoring the network and checking the file system for suspicious changes will discover misbehaving code. The Prevasio solution Security tools designed for statically loaded code aren’t very helpful with containers. Prevasio has created a new approach that analyzes containers without making any assumptions about their safety. It loads them into a sandboxed environment where they can’t do any harm and analyzes them.The analysis includes the following: Scanning of components for known vulnerabilities Automated pen-test attacks Behavioral analysis of running code Traffic analysis to discover suspicious data packets Machine learning to identify malicious binaries The analysis categorizes an image as benign,vulnerable, exploitable, dangerous, or harmful. The administrator looks at agraph to identify any problems visually, without digging through logs. They can tell at a glance whether an image is reasonably safe to run, needs to be sent back for fixes, or should be discarded on the spot. If you look at competing container security solutions, you’ll find that the key is runtime technology. Static analysis, vulnerability scans, and signature checking won’t get you enough protection by themselves. Prevasio gives you the most complete and effective checking of container images, helping you to avoid threats to your data and your business.

Network Segmentation Navigating the Cybersecurity Horizon in 2024 Prof. Avishai Wool 2 min read Prof. Avishai Wool Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 12/17/23 Published The persistence of sophisticated ransomware In 2023, organizations faced a surge in ransomware attacks, prompting a reevaluation of cybersecurity readiness. The focus on high-value assets and critical infrastructure indicated an escalating threat landscape, demanding stronger preemptive measures. This trend is expected to continue in 2024 as cybercriminals exploit vulnerabilities. Beyond relying on technology alone, organizations must adopt strategies like Zero Trust and Micro-segmentation for comprehensive preparedness, fortifying data security. A resolute and practical response is crucial to safeguard critical assets in the evolving cybersecurity landscape. DevSecOps Integration DevSecOps is set to become a cornerstone in software development, integrating security practices proactively. As Infrastructure as a Service (IaaS) popularity rises, customizing security settings becomes challenging, necessitating a shift from network perimeter reliance. Anticipating an “Always-on Security” approach like Infrastructure as Code (IaC), companies can implement policy-based guardrails in the CI/CD pipeline. If risks violating the guardrails are identified, automation should halt for human review. Cloud-Native Application Protection Platforms (CNAPP): The CNAPP market has advanced from basic Cloud Security Posture Management (CSPM) to include varied vulnerability and malware scans, along with crucial behavioral analytics for cloud assets like containers. However, few vendors emphasize deep analysis of Infrastructure as a Service (IaaS) networking controls in risk and compliance reporting. A more complete CNAPP platform should also provide comprehensive analytics of cloud applications’ connectivity exposure. Application-centric approach to network security will supersede basic NSPM Prepare for the shift from NSPM to an application-centric security approach, driven by advanced technologies, to accelerate in 2024. Organizations, grappling with downsizing and staff shortages, will strategically adopt this holistic approach to improve efficiency in the security operations team. Emphasizing knowledge retention and automated change processes will become crucial to maintain security with agility. AI-based enhancements to security processes Generative AI, as heralded by Chat-GPT and its ilk, has made great strides in 2023, and has demonstrated that the technology has a lot of potential. I think that in 2024 we will see many more use cases in which this potential goes from simply being “cool” to a more mature technology that is brought to market to bring real value to owners of security processes. Any use case that involves analyzing, summarizing, or generalizing text, can potentially benefit from a generative AI assist. The trick will be to do so in ways that save human time, without introducing factual hallucinations.

Tags Share this article 12/22/20 Published In the previous parts of our blog ( part I and part II ), we have described the most important parts of the Sunburst backdoor functionality and its Domain Generation Algorithm (DGA). This time, let’s have a deeper look into the passive DNS requests reported by Open-Source Context and Zetalytics . The valid DNS requests generated by the malware fall into 2 groups: DNS requests that encode a local domain name DNS requests that encode data The first type of DNS requests allows splitting long domain names into separate requests. These requests are generated by the malware’s functions GetPreviousString() and GetCurrentString() . In general, the format of a DNS request that encodes a domain name may look like: USER_ID.NUM.COMPUTER_DOMAIN[.]appsync-api.us-west-2[.]avsvmcloud[.]com where: USER_ID is an 8-byte user ID that uniquely identifies a compromised host, encoded as a 15-character string NUM is a number of a domain name – either 0 or 1, encoded as a character COMPUTER_DOMAIN is an encoded local computer domain Let’s try decoding the following 3 DNS requests: olc62cocacn7u2q22v02eu.appsync-api.us-west-2.avsvmcloud.com r1qshoj05ji05ac6eoip02jovt6i2v0c.appsync-api.us-west-2.avsvmcloud.com lt5ai41qh5d53qoti3mkmc0.appsync-api.us-west-2.avsvmcloud.com String 1 Let’s start from the 1st string in the list: olc62cocacn7u2q22v02eu.appsync-api.us-west-2.avsvmcloud.com. In this string, the first 15-character string is an encoded USER_ID : “olc62cocacn7u2q” . Once it is base-64 decoded, as explained in the previous post, it becomes a 9-byte byte array: 86 7f 2f be f9 fb a3 ae c4 The first byte in this byte array is a XOR key: 0x86 . Once applied to the 8 bytes that follow it, we get the 8-byte user ID – let’s take a note and write it down, we will need it later: f9 a9 38 7f 7d 25 28 42 Next, let’s take the NUM part of the encoded domain: it’s a character “2” located at the position #15 (starting from 0) of the encrypted domain. In order to decode the NUM number, we have to take the first character of the encrypted domain, take the reminder of its division by 36 , and subtract the NUM ‘s position in the string “0123456789abcdefghijklmnopqrstuvwxyz” : num = domain[0] % 36 – “0123456789abcdefghijklmnopqrstuvwxyz”.IndexOf(domain.Substring(15, 1)); The result is 1 . That means the decrypted domain will be the 2nd part of a full domain name. The first part must have its NUM decoded as 0. The COMPUTER_DOMAIN part of the encrypted domain is “2v02eu” . Once decoded, using the previously explained method, the decoded computer domain name becomes “on.ca” . String 2 Let’s decode the second passive DNS request from our list: r1qshoj05ji05ac6eoip02jovt6i2v0c.appsync-api.us-west-2.avsvmcloud.com Just as before, the decoded 8-byte user ID becomes: f9 a9 38 7f 7d 25 28 42 The NUM part of the encoded domain, located at the position #15 (starting from 0), is a character “6” . Let’s decode it, by taking the first character ( “r” = 114 ), take the reminder of its division by 36 ( 114 % 36 = 6 ), and subtracting the position of the character “6” in the “0123456789abcdefghijklmnopqrstuvwxyz” , which is 6 . The result is 0 . That means the decrypted domain will be the 1st part of the full domain name. The COMPUTER_DOMAIN part of the encrypted domain is “eoip02jovt6i2v0c” . Once decoded, it becomes “city.kingston.” Next, we need to match 2 decrypted domains by the user ID, which is f9 a9 38 7f 7d 25 28 42 in both cases, and concatenate the first and the second parts of the domain. The result will be “city.kingston.on.ca” . String 3 Here comes the most interesting part. Lets try to decrypt the string #3 from our list of passive DNS requests: lt5ai41qh5d53qoti3mkmc0.appsync-api.us-west-2.avsvmcloud.com The decoded user ID is not relevant, as the decoded NUM part is a number -29 . It’s neither 0 nor 1 , so what kind of domain name that is? If we ignore the NUM part and decode the domain name, using the old method, we will get “thx8xb” , which does not look like a valid domain name. Cases like that are not the noise, and are not some artificially encrypted artifacts that showed up among the DNS requests. This is a different type of DNS requests. Instead of encoding local domain names, these types of requests contain data. They are generated by the malware’s function GetNextStringEx() . The encryption method is different as well. Let’s decrypt this request. First, we can decode the encrypted domain, using the same base-64 method, as before . The string will be decoded into 14 bytes: 7c a5 4d 64 9b 21 c1 74 a6 59 e4 5c 7c 7f Let’s decode these bytes, starting from the 2nd byte, and using the first byte as a XOR key. We will get: 7c d9 31 18 e7 5d bd 08 da 25 98 20 00 03 In this array, the bytes marked in yellow are an 8-byte User ID, encoded with a XOR key that is selected from 2 bytes marked in red. Let’s decode User ID: for ( int i = 0 ; i < 8 ; i++) { bytes[i + 1 ] ^= bytes[ 11 - i % 2 ]; } The decoded byte array becomes: 7c f9 a9 38 7f 7d 25 28 42 25 98 20 00 03 The User ID part in marked in yellow. Does it look familiar? Indeed, it’s the same User ID we’ve seen before, when we decoded “city.kingston.on.ca” . The next 3 bytes marked in red are: 25 98 20 . 2 0x59820 The first number 2 stands for the size of data that follows – this data is 00 03 (selected in green). The number 0x59820 , or 366,624 in decimal, is a timestamp. It’s a number of 4-second periods of time since 1 January 2010. To obtain the real time stamp, we need to multiple it by 15 to get minutes, then add those minutes to 1 January 2010: var date = ( new DateTime( 2010 , 1 , 1 , 0 , 0 , 0 , DateTimeKind.Utc)).AddMinutes(timestamp * 15 ); For the number 0x59820 , the time stamp becomes 16 July 2020 12:00:00 AM – that’s the day when the DNS request was made. The remaining 2 bytes, 00 03 , encrypt the state of 8 security products, to indicate whether each one of them is running or whether it is stopped. The 8 security products are: Windows Live OneCare / Windows Defender Windows Defender Advanced Threat Protection Microsoft Defender for Identity Carbon Black CrowdStrike FireEye ESET F-Secure 2 states for 8 products require 2 * 8 = 16 bits = 2 bytes. The 2 bytes 00 03 in binary form are: 00 00 00 00 00 00 00 11 Here, the least-significant bits 11 identify that the first product in the list, Windows Live OneCare / Windows Defender, is reported as ‘running’ ( 1 ) and as ‘stopped’ ( 1 ). Now we know that apart from the local domain, the trojanised SolarWinds software running on the same compromised host on “city.kingston.on.ca” domain has also reported the status of the Windows Defender software. What Does it Mean? As explained in the first part of our description, the malware is capable of stopping the services of security products, be manipulating registry service keys under Administrator account. It’s likely that the attackers are using DNS queries as a C2 channel to first understand what security products are present. Next, the same channel is used to instruct the malware to stop/deactivate these services, before the 2nd stage payload, TearDrop Backdoor, is deployed. Armed with this knowledge, let’s decode other passive DNS requests, printing the cases when the compromised host reports a running security software. NOTES: As a private case, if the data size field is 0 or 1 , the timestamp field is not followed with any data. Such type of DNS request is generated by the malware’s function GetNextString() . It is called ‘a ping’ in the listing below. If the first part of the domain name is missing, the recovered domain name is pre-pended with ‘*’ . The malware takes the time difference in minutes, then divides it by 30 and then converts the result from double type to int type; as a result of such conversion, the time stamps are truncated to the earliest half hour. 2D82B037C060515C SFBALLET Data: Windows Live OneCare / Windows Defender [running] 11/07/2020 12:00:00 AM Pings: 12/07/2020 12:30:00 AM 70DEE5C062CFEE53 ccscurriculum.c Data: ESET [running] 17/04/2020 4:00:00 PM Pings: 20/04/2020 5:00:00 PM AB902A323B541775 mountsinai.hospital Pings: 4/07/2020 12:30:00 AM 9ACC3A3067DC7FD5 *ripta.com Data: ESET [running] 12/09/2020 6:30:00 AM Pings: 13/09/2020 7:30:00 AM 14/09/2020 9:00:00 AM CB34C4EBCB12AF88 DPCITY.I7a Data: ESET [running] 26/06/2020 5:00:00 PM Pings: 27/06/2020 6:30:00 PM 28/06/2020 7:30:00 PM 29/06/2020 8:30:00 PM 29/06/2020 8:30:00 PM E5FAFE265E86088E *scroot.com Data: CrowdStrike [running] 25/07/2020 2:00:00 PM Pings: 26/07/2020 2:30:00 PM 26/07/2020 2:30:00 PM 27/07/2020 3:00:00 PM 27/07/2020 3:00:00 PM 426030B2ED480DED *kcpl.com Data: Windows Live OneCare / Windows Defender [running] 8/07/2020 12:00:00 AM Carbon Black [running] 8/07/2020 12:00:00 AM Full list of decoded pDNS requests can be found here .

Tags Share this article 9/12/23 Published With expertise in data management, search algorithms, and AI, Google has created a cloud platform that excels in both performance and efficiency. The advanced machine learning, global infrastructure, and comprehensive suite of services available in Google Cloud demonstrates Google’s commitment to innovation. Many companies are leveraging these capabilities to explore new possibilities and achieve remarkable outcomes in the cloud. When large companies decide to locate or move critical business applications to the cloud, they often worry about security. Making decisions to move certain applications to the cloud should not create new security risks. Companies are concerned about things like hackers getting access to their data, unauthorized people viewing or tampering with sensitive information, and meeting compliance regulations. To address these concerns, it’s important for companies to implement strong security measures in the cloud, such as strict access controls, encrypting data, constantly monitoring for threats, and following industry security standards. Unfortunately, even with the best tools and safeguards in place it is hard to protect against everything. Human error plays a major part in this and can introduce threats with a few small mistakes in configuration files or security rules that can create unnecessary security risks. The CloudFlow solution from AlgoSec is a network security management solution designed for cloud environments. It provides clear visibility, risk analysis, and helps identify unused rules to help with policy cleanup across multi-cloud deployments. With CloudFlow, organizations can manage security policies, better understand risk, and enhance their overall security in the cloud. It offers centralized visibility, helps with policy management, and provides detailed risk assessment. With Algosec Cloud, and support for Google Cloud, many companies are gaining the following new capabilities: Improved visibility Identifying and reduce risk Generating detailed risk reports Optimizing existing policies Integrating with other cloud providers and on-premise security devices Improve overall visibility into your cloud environments Gain clear visibility into your Google Cloud, Inventory, and network risks.

Security Policy Management with Professor Wool Firewall Management 201 Firewall Management with Professor Wool is a whiteboard-style series of lessons that examine the challenges of and provide technical tips for managing security policies in evolving enterprise networks and data centers. Lesson 1 In this lesson, Professor Wool discusses his research on different firewall misconfigurations and provides tips for preventing the most common risks. Examining the Most Common Firewall Misconfigurations Watch Lesson 2 In this lesson, Professor Wool examines the challenges of managing firewall change requests and provides tips on how to automate the entire workflow. Automating the Firewall Change Control Process Watch Lesson 3 In this lesson, Professor Wool offers some recommendations for simplifying firewall management overhead by defining and enforcing object naming conventions. Using Object Naming Conventions to Reduce Firewall Management Overhead Watch Lesson 4 In this lesson, Professor Wool examines some tips for including firewall rule recertification as part of your change management process, including questions you should be asking and be able to answer as well as guidance on how to effectively recertify firewall rules Tips for Firewall Rule Recertification Watch Lesson 5 In this lesson, Professor Wool examines how virtualization, outsourcing of data centers, worker mobility and the consumerization of IT have all played a role in dissolving the network perimeter and what you can do to regain control. Managing Firewall Policies in a Disappearing Network Perimeter Watch Lesson 6 In this lesson, Professor Wool examines some of the challenges when it comes to managing routers and access control lists (ACLs) and provides recommendations for including routers as part of your overall security policy with tips on change management, auditing and ACL optimization. Analyzing Routers as Part of Your Security Policy Watch Lesson 7 In this lesson, Professor Wool examines the complex challenges of accurately simulating network routing, specifically drilling into three options for extracting the routing information from your network: SNMP, SSH and HSRP or VRPP. Examining the Challenges of Accurately Simulating Network Routing Watch Lesson 8 In this lesson, Professor Wool examines the complex challenges of accurately simulating network routing, specifically drilling into three options for extracting the routing information from your network: SNMP, SSH and HSRP or VRPP. NAT Considerations When Managing Your Security Policy Watch Lesson 9 In this lesson, Professor Wool explains how you can create templates - using network objects - for different types of services and network access which are reused by many different servers in your data center. Using this technique will save you from writing new firewall rules each time you provision or change a server, reduce errors, and allow you to provision and expand your server estate more quickly. How to Structure Network Objects to Plan for Future Policy Growth Watch Lesson 10 In this lesson, Professor Wool examines the challenges of migrating business applications and physical data centers to a private cloud and offers tips to conduct these migrations without the risk of outages. Tips to Simplify Migrations to a Virtual Data Center Watch Lesson 11 In this lesson, Professor Wool provides the example of a virtualized private cloud which uses hypervisor technology to connect to the outside world via a firewall. If all worksloads within the private cloud share the same security requirements, this set up is adequate. But what happens if you want to run workloads with different security requirements within the cloud? Professor Wool explains the different options for filtering traffic within a private cloud, and discusses the challenges and solutions for managing them. Tips for Filtering Traffic within a Private Cloud Watch Lesson 12 In this lesson Professor Wool discusses ways to ensure that your security policy on your primary site and on your disaster recovery (DR) site are always sync. He presents multiple scenarios: where the DR and primary site use the exact same firewalls, where different vendor solutions or different models are used on the DR site, and where the IP address is or is not the same on the two sites. Managing Your Security Policy for Disaster Recovery Watch Lesson 13 In this lesson, Professor Wool highlights the challenges, benefits and trade-offs of utilizing zero-touch automation for security policy change management. He explains how, using conditional logic, its possible to significantly speed up security policy change management while maintaining control and ensuring accuracy throughout the process. Zero-Touch Change Management with Checks and Balances Watch Lesson 14 Many organizations have different types of firewalls from multiple vendors, which typically means there is no single source for naming and managing network objects. This ends up creating duplication, confusion, mistakes and network connectivity problems especially when a new change request is generated and you need to know which network object to refer to. In this lesson Profession Wool provides tips and best practices for how to synchronize network objects in a multi-vendor environment for both legacy scenarios, and greenfield scenarios. Synchronized Object Management in a Multi-Vendor Environment Watch Lesson 15 Many organizations have both a firewall management system as well as a CMDB, yet these systems do not communicate with each other and their data is not synchronized. This becomes a problem when making security policy change requests, and typically someone needs to manually translate the names used by in the firewall management system to the name in the CMDB, which is a slow and error-prone process, in order for the change request to work. In this lesson Professor Wool provides tips on how to use a network security policy management to coordinate between the two system, match the object names, and then automatically populate the change management process with the correct names and definitions. How to Synchronize Object Management with a CMDB Watch Lesson 16 Some companies use tools to automatically convert firewall rules from an old firewall, due to be retired, to a new firewall. In this lesson, Professor Wool explains why this process can be risky and provides some specific technical examples. He then presents a more realistic way to manage the firewall rule migration process that involves stages and checks and balances to ensure a smooth, secure transition to the new firewall that maintains secure connectivity. How to Take Control of a Firewall Migration Project Watch Lesson 17 PCI-DSS 3.2 regulation requirement 6.1 mandates that organizations establish a process for identifying security vulnerabilities on the servers that are within the scope of PCI. In this new lesson, Professor Wool explains how to address this requirement by presenting vulnerability data by both the servers and the by business processes that rely on each server. He discusses why this method is important and how it allows companies to achieve compliance while ensuring ongoing business operations. PCI – Linking Vulnerabilities to Business Applications Watch Lesson 18 Collaboration tools such as Slack provide a convenient way to have group discussions and complete collaborative business tasks. Now, these automated chatbots can be used for answering questions and handling tasks for development, IT and infosecurity teams. For example, enterprises can use chatbots to automate information-sharing across silos, such as between IT and application owners. So rather than having to call somebody and ask them “Is that system up? What happened to my security change request?” and so on, tracking helpdesk issues and the status of help requests can become much more accessible and responsive. Chatbots also make access to siloed resources more democratic and more widely available across the organization (subject, of course to the necessary access rights). In this video, Prof. Wool discusses how automated chatbots can be used to help a wide range of users for their security policy management tasks – thereby improving service to stakeholders and helping to accelerate security policy change processes across the enterprise.
