The internet world was recently taken over by a serious network/application security issue called Log4j – tracked as “CVE-2021-44228”. The US government cybersecurity agency had termed it as a major threat. This vulnerability could allow the attacker to do a remote-controlled execution (RCE). An RCE is one of the most feared vulnerabilities and poses a significant security issue to all Java-based applications globally. What followed was the rolling out of software patches and upgrades by network engineers to fix this issue.
Such vulnerabilities have again highlighted the challenge for network operators to identify vulnerable servers that need immediate protection. The threat of CVEs is so grave that in 2021 alone, there were close to 45,000 reported vulnerabilities.
According to Risk Based Security’s data breach report, there were 1,767 publicly reported breaches in the first six months of 2021, down 24% from last year. In the United States, the number of reported breaches increased by 1.5 percent, with 18.8 billion information exposed this year, down 32 percent from the 27.8 billion records exposed in the first half of 2020.
How does ADC+ help in managing Big IP CVE vulnerabilities?
ADC+ automation workflows can be scheduled or run on-demand to scan for CVEs regularly. When it’s necessary to assess the security posture, Security teams can use a User Interface (GUI) to access a detailed report of all CVEs and the essential remediation and mitigation methods. This automated method might help validate remediation and ensure current security updates. These workflows provide a remedial patch management approach that can help Network and Security teams save time if a specific CVE requires an upgrade of your ADCs.
Here are some key benefits of performing vulnerability checks using ADC+
- Automated discovery of the CVEs across devices
ADC+ can scan inventory devices from multiple vendors (F5, NGINX, AVI), generates real-time data from the devices, and displays it in structured, easy-to-understand reports. Administrators can use these reports to spot outliers and investigate threats before they have any chance to affect the system.
- Improved data collection and analysis for better governance
ADC+ empowers you to run automated CVE detection scans across the ADC devices within your infra and get notified of vulnerabilities and Severities (from CVE sites). It also lists actionable reports on vulnerable devices and remediates (upgrades to the recommended versions) while ensuring adherence to compliance standards.
- Detect and generate CVE reports with severities
You can schedule or [Run automation workflows on-demand to check for CVEs] at regular intervals when required to assess the security posture. The Security team can use a fully-featured report of flaws found via a user-friendly User Interface (GUI).
- Automated application of patches and fixes
Patch management is still a manual process, with fixes deployed and evaluated separately on each device. ADC+ automates patch management by integrating with the vendor to receive patches, scanning the network for devices that need to be patched, applying and validating the patches, and generating a status report with the updates.
- Alert based incident mechanism
ADC+ assists in prioritizing incidents and streamlining priorities and approvals. It sends out real-time notifications by phone and other media, allowing for faster staff assignment and problem resolution, reducing the MTTR dramatically.
- Context-aware problem solving
Before executing the remediation workflow, ADC+ considers the state, status, and performance of systems across environments and platforms, ensuring that the remedy delivered has no negative influence on the infrastructure.
- Security and authorization management
ADC+ has a secure vault where you can store encrypted device authentication credentials and identity tokens, which can subsequently be used to provide secure access to users and devices via a unified ACL.
AppViewX ADC+ simplifies application discovery across environments, performs automated backups, do periodic compliance checks (pre-and post-validation), and reports non-compliance through built-in connections within ITSM systems, making it easier to upgrade your existing system setups. It has self-serviceable upgrade templates built-in, making the upgrade or patching procedure easier. Most of the BIG-IP versions are supported by ADC+, ensuring a quick, error-free, and smooth update.
