Challenge: There is a huge shortfall in the number of cyber security professionals needed to fill existing cyber security job vacancies. The gap stood at 4.07 million professionals in 2019. With such scarcity, SOCs walk a tight rope daily with a high risk of team members getting overwhelmed.
Solution: Organizations should look within and consider upskilling employees to fill gaps in their SOC team. All roles in the SOC should have a backup who has the expertise needed to hold the fort if the position suddenly falls vacant. (or learn to pay what skills are worth instead of using the lowest price resource they can find...)
Challenge: Network defense is a key component of an organization’s cyber security strategy. It needs special attention since sophisticated actors have the tools and knowhow required to evade traditional defenses such as firewalls and endpoint security.
Solution: Deploy tools that have anomaly detection and/or machine learning capabilities and can identify new threats.
Voluminous Data and Network Traffic
Challenge: The amount of network traffic and data the average organization handles is enormous. With such astronomical growth in data volume and traffic comes a rising difficulty in analyzing all this information in real time.
Solution: SOCs rely on automated tools to filter, parse, aggregate and correlate information to keep manual analysis to the bare minimum.
Challenge: In many security systems, anomalies occur with some regularity. If the SOC relies on unfiltered anomaly alerts, it’s easy for the sheer volume of alerts to be overwhelming. Many alerts may fail to provide the context and intelligence needed to investigate thus distracting teams from real problems.
Solution: Configure monitoring content and alert ranking to distinguish between a low fidelity alerts and high fidelity alerts. Use behavioral analytics tools to ensure the SOC team is focused on addressing the most unusual alerts first.
Challenge: Conventional signature-based detection, endpoint detection and firewalls cannot identify an unknown threat.
Solution: SOCs can improve their signature, rules and threshold based threat detection solutions by implementing behavior analytics to find unusual behavior.
Security Tool Overload
Challenge: In their effort to catch every possible threat, many organizations procure multiple security tools. These tools are often disconnected from each other, have a limited scope and do not have the sophistication to identify complex threats.
Solution: Focus on effective countermeasures with a centralized monitoring and alerting platform.
