Proactive Intruder Monitoring
As a network administrator or CISO, it’s important to think strategically and holistically about securing your systems. It’s crucial that we understand security not as a discrete event but as a continuous, ever-changing process. Taking the following tasks and areas into account can go a long way in protecting your systems and data.
1) Shrink Your Attack Surface
Your top priority is to proactively prevent breaches from occurring in the first place. Tactically executing on that idea means reducing the attack surface of your system by using flexible golden build security standards, and only allowing those ports and protocols which internal and external users absolutely need to access behind a firewall.
Maintaining strong passwords that are rotated on a regular basis for operating system and application level access can also harden your systems against intrusion attempts.
2) Maintain Continuous Compliance with Vulnerability Scans
Intrusion Detection Systems (IDS) can provide information about an attack that is already underway, or one that has already taken place, but administrators also need ways of continuously monitoring vulnerabilities and solving them. This is where persistent, active monitoring comes in. CyberSana takes a proactive approach to security, allowing for automated audits that can reveal and repair problems in real-time. Through our intuitive dashboard you will receive greater visibility into configuration issues, vulnerabilities and more in a single, easy to use system — not just for an individual device, but for your entire infrastructure.
CyberSana can schedule audits for your entire Linux server infrastructure, your firewalls and more. Within moments, you can view issues on topics as wide-ranging as directory permissions, SELinux policy enforcement, packet capture, SSH timeout policies, and reverse path filtering. Even better, you can define rules for auto-mitigation: the configurations can be fixed automatically, and other countermeasures can be triggered. Regularly scheduled audits can also reveal unusual activity that could be symptomatic of a breach — unexpectedly high memory usage, fan speed, CPU temperatures and more.
3) Gain Visibility with Service Monitoring and Device Detection
CyberSana’s power to conduct continuous across-the-board monitoring isn’t limited to audits. In the “monitoring” section of the dashboard, you can take advantage of both internal and external availability checks on all services and devices. Your team can respond as soon as signs of a failure or attack appear. Additionally, having easy access to your network and server devices is critical for identifying and recording investigation of malicious activity.
The unexpected presence of a new device or service on the network can be another indication that an attack is underway or has already occurred, as can changes in the availability of existing services. CyberSana supports device auto-discovery, so you can see not only the devices on your network but how long they have been up and active, which ports they have open, and which policies are in effect.
The security ecosystem is constantly changing, with new attacks and defenses developed every day. Providing your systems with the very best protection means moving beyond a static approach to security and taking advantage of a proactive, real-time approach. CyberSana’s automated audits, availability monitoring, device discovery and auto-mitigation give administrators the power and speed to fight back.
