Why having SOC is key?
A security operations center can help mitigate the effects of a data breach, but its business benefits are far greater.
The purpose of SOC is to gain a complete view of the threats facing the business, including not only the different types of endpoints, servers and software, but also third-party services and traffic flowing between these assets.
All actions taken to make successful attacks more difficult, including regularly maintaining and updating existing systems; updating firewall policies; patching vulnerabilities; whitelisting, blacklisting and application protection.
SOC tools scan the network 24/7 to flag any suspicious activity. Round-the-clock monitoring allows the team to be immediately notified of emerging threats, giving them the best chance to prevent or mitigate damage.
When monitoring tools issue alerts, it’s the SOC’s responsibility to scrutinize each one, reject any false ones, and determine how aggressive the actual threats are and what they might be targeting.
The SOC acts as the first force, performing actions such as shutting down or isolating endpoints, terminating harmful processes (or preventing them from running), deleting files, and more. The goal is as little impact on business continuity as possible.
After an incident, the SOC will work to restore systems and lost or compromised data. This can include deleting and restarting endpoints, reconfiguring systems or, in the case of ransomware attacks, using backups. When successful, this step will return the network to the state it was in before the incident.
Cybercriminals are constantly improving their tools and tactics – and to stay one step ahead, a SOC must continually implement improvements. This can also include practices like red-teaming and purple-teaming.
Many SOC processes are guided by established best practices, but some are driven by compliance requirements. The SOC is responsible for regularly auditing systems to ensure compliance with such regulations as may be required by the organization, by industry or by governing bodies. Examples of these regulations include GDPR and ISO.
