Incidents: Containment, Eradication and Recovery
Posted: Mon Feb 10, 2025 9:15 am
Training: Employees, even those outside the IT or security department, should be aware of cybersecurity and trained. It is rare that a security incident does not affect a wider group of employees. Training will also help them respond to and prevent incidents.
To prevent malware from spreading laterally across a network, organizations should already have intent-based segmentation and zero trust protocols in place. Intent-based segmentation logically separates systems, devices, and data based on business requirements and is critical to preventing a system-wide incident.
Once malware or other elements of compromise are identified, care must be taken to remove them completely from the network. Tools that modify shared libraries or files, modify applications or code, or exploit existing software—a technique known as “living off the land”—can make identifying and removing all attack elements particularly challenging. As a result, action must be taken quickly to prevent the attacker from compromising the system again. This is accomplished by using the information finland mobile database from previous steps and immediately addressing the issues that led to the breach, such as reconfiguring the device, installing a missing patch, or resetting compromised credentials.
Finally, once an incident has been contained and resolved, recovery must be performed using correct backups. Recovery teams must be able to return critical systems to working order as quickly as possible. IT teams should also be aware that embedded threats can be difficult to completely eliminate, especially those designed to avoid detection, so it is always a good idea to increase security monitoring in the weeks following a breach to ensure that the threat has been completely eliminated.
