What Role  Does a SOC Play Against Cyberattacks?

July 12, 2022

The role of a SOC in protecting an organisation's digital assets is vital. This team of security professionals must be aware of the threat landscape and potential cyberattack targets. It must be up-to-date on all company assets, including cloud and third-party services. Perhaps the most crucial role of a SOC is to respond to cyberattacks. Its job is to detect threats and respond to them as quickly and effectively as possible.

 

Keeping a SOC team up to date on cyberattacks

Keeping a SOC team up to date with cyberattacks is crucial to detecting and responding to these attacks. The SOC collects and reviews logs to determine "normal" network activity and identifies threats. The data from these logs can be used to remediate after an attack or to improve security policies. In addition, many SOCs use SIEM to aggregate and correlate data feeds from operating systems, firewalls, and endpoints.

Network traffic and data volume in a typical organization is enormous. Automated tools for SOC analysis make it easy to manage data and alerts centrally. However, unfiltered signals can become overwhelming as many of them are false positives or lack context. SOC teams must remain informed of cyberattacks and the latest trends to address this problem. Low-quality alerts divert team members from actual security incidents.

Keeping a SOC team up to date with cyberattacks requires ongoing improvement. For example, cybercriminals constantly refine their tools and tactics. SOCs can conduct post-mortem investigations and realistic practice sessions to identify gaps in security processes.

Most organizations use a combination of tools to provide a SOC team with data and alerts. These tools may be in-house or available in an external environment. However, if a team is overworked, they may experience alert fatigue, which is detrimental to their effectiveness. Furthermore, the number of false positives will waste precious time and divert attention from actual cyberattacks.

The bulk of a SOC team consists of analysts. They detect threats and act to remedy them. They may also need to implement security measures or contribute to a disaster recovery plan. In many cases, analysts work after business hours, making them essential to a security program's success. Senior analysts look into affected systems, examine intelligence reports to determine vulnerabilities, and develop plans to remedy the damage. As the threat becomes more advanced, these analysts also take the lead in disaster recovery plans.

The SOC team monitors an organization's network twenty-four hours a day, seven days a week. Because cyber criminals do not follow regular business hours, they are more likely to attack an organization during holidays and weekends. By responding quickly to these attacks, a security team can ensure the safety of sensitive data. Proactive monitoring and analysis flags suspicious activity before it causes significant damage.

 

Reporting findings to key stakeholders

A SOC is responsible for monitoring and reporting on network activity, utilizing various tools to monitor anomalies and alert staff to potential security threats. Its role goes beyond handling network problems that pop up from time to time, though. It reports findings to key stakeholders and the CIO, keeping the business running smoothly and ensuring it is protected. To support its clients safe and secure, SOCs should maintain logs detailing all network activity.

In addition to reporting findings to key stakeholders, the SOC performs investigations and implements security measures. Security analysts may also play a vital role in disaster recovery plans and may have to respond after regular business hours. The SOC's senior analysts review affected systems and intelligence reports to investigate the nature of the threat. They may also implement mitigation strategies and develop plans to restore or repair assets damaged by an attack.

The SOC receives information from the main SOC. Its employees are responsible for maintaining signatures and protecting systems from IPS systems. It also reports to key and other stakeholders as part of its role against cyberattacks. While SOCs offer many cyber security services, protecting a business with an extensive information system or web presence must be worth the investment.

Ideally, a SOC would have visibility into all areas of an organization. It would also have access to encrypted data and systems controlled by third parties. A SOC would report findings to key stakeholders and share them with the rest of the company. These reports serve as a bridge between the SOC and the rest of the organization. They also report findings to key stakeholders, which can help prevent problems before they impact customers.

In addition to reporting findings to key stakeholders, a SOC must constantly improve and evaluate security processes. By carrying out practical practice sessions and post-mortem investigations, it can identify vulnerabilities in security processes and make recommendations for improvements. Besides, SOCs help organizations adhere to industry-standard cybersecurity policies, such as ISO 27001x, the General Data Protection Regulation, and the NIST Cybersecurity Framework.

A SOC should report to key stakeholders to share its findings and lessons. In the aftermath of an attack, the public internalizes the details. This is reflected in media reports, but later reports will include more element. By then, the damage had been done. The public is already scared. They will react negatively and may not want to be trusted with their data.

Security operations centres are responsible for monitoring systems and activity around the clock to identify security incidents. With this constant monitoring, organizations have an edge in defending against attacks. Verizon's annual data breach investigations report details the gap between attackers' time of compromise and the time it takes enterprises to detect an attack. These capabilities make security operations centres a necessary addition to any cybersecurity strategy.

 

Adapting cybersecurity architectures

A SOC is responsible for triaging and responding to security incidents. During an incident, the SOC may reconfigure endpoints or wipe data. During the recovery process, it may deploy backups to circumvent ransomware. Successful restoration returns the network to the pre-attack state. To keep the network safe from future threats, the SOC must constantly monitor the security of critical assets.

As the threat landscape changes, securing business operations becomes more complex. Traditional reactive approaches to cybersecurity are no longer sufficient, as new threats always emerge. Organizations must adopt proactive and adaptive approaches to keep pace with evolving threats and protect critical business operations. Further, organizations must establish a risk assessment framework and implement hands-on practices such as red-teaming and purple-teaming.

The evolution of modern business has led to the need for SOCs to develop advanced capabilities to protect their businesses. The agile nature of today's business environment makes it vulnerable to high-impact, sophisticated threats that may result in lost revenue and damaged reputations. Adaptive security architectures enable enterprises to counter-attack cyberattacks before they happen and minimize the impact of these attacks. The detective layer of adaptive security helps identify threats that may have been missed by the preventative layer, while the prevention layer detects those that have already happened. By constantly assessing risk, the SOC can provide proportional enforcement.

 

Security architectures for SOCs involve three main components: people, processes, and tools. These components must ensure that assets are protected from cyber threats and that security decision-making is consistent across the IT-sphere. Adapting cybersecurity architectures for SOCs is an ongoing process that must be continually updated and modified. The security architecture will no longer serve its purpose if it is not correctly updated.

A SOC's security architecture should consider the risks of a specific cyberattack. It should have a low attack surface, be covertly stored, and have end-to-end encryption to protect sensitive data. In addition to this, it should use Moving-Target defences to combat cyberattacks. Security architects are particularly adept at identifying potential threats. They understand computer and network systems enough to create a comprehensive cybersecurity architecture plan and oversee its implementation.

Today's cybersecurity challenges have forced organizations to develop a security mesh that can scale and adapt to evolving threats. Cybersecurity mesh architectures simplify security infrastructure design, deployment, and maintenance. The distributed cybersecurity mesh also enables organizations to engage with consumers more rapidly. So, cybersecurity mesh architectures may be the right solution for you if you are looking for an answer.
