Cybersecurity can be centred in a SOC, which is a team of people who monitor for threats, vulnerabilities or unusual activities.
A SOC is an entire business unit that is entirely dedicated to cyber security. The group monitors traffic flow and watches for threats and attacks, and are an essential team for companies of all sizes—all companies are susceptible to data breaches and cyberattacks.
A SOC focuses entirely on a company’s security, helping to ensure that less downtime and faster incident responses. There are also monitoring tools and SOC solutions that build redundancies into their models to prevent any downtime.
One data breach can be enough to turn customers away from an organisation. Customers want to work with an organisation that takes security seriously. Avoiding breaches and putting a strong emphasis on security can help customers have peace of mind as they do business with a company.
The most recent SOC models offer software as a service (SaaS) programmes that are subscription-based. The SOC’s team of experts build a cyber security strategy, ideally operation 24/7, while consistently monitoring networks and endpoints. In the event that a threat or vulnerability is discovered, the SOC will work with onsite IT teams to create a response and investigate the source.
A company hosts their own cyber security team.
A security team that works remotely.
Larger, more high-level groups that oversee smaller SOCs.
A company’s IT department teams up with an external SOC vendor to manage security together.
SOC managers lead their respective organisation at the top-level, which includes workforce management, budgeting and setting priorities. They usually work one step below a chief information security officer (CISO).
They react to and analyse security alerts the moment they occur. They typically use a range of monitoring tools to analyse the severity of alerts and they engage once an alert has been labelled an actionable incident.
Threat hunters proactively search for threats and weaknesses across a network. Ideally, they identify threats and vulnerabilities before they can impact the business.
The analyst who investigates and gathers information after an attack, then preserves the digital evidence for future preventative measures.
They are responsible for escalating potential threats after analysing all threats and determining the levels of severity.
The SOC is responsible for devices, applications and processes, as well as defensive tools to ensure continued protection.
It is the SOC’s function to have a complete view of a business’s critical data, including software, servers, endpoints and third-party services, along with all of the traffic being exchanged between the assets.
A SOC uses agility to protect a company. They develop a strong level of expertise of all possible tools in cyber security and workflows that the SOC uses.
Responses can be quickly executed, but a well-equipped team still needs to prepare and take preventative measures to ensure cyber resilience.
SOC professionals stay informed on the latest in cyber security innovations and the latest threats. Staying constantly updated can help with the continuous evolution of their security roadmap, which can act as a guide for the company’s security efforts moving forward.
Prevention means taking all necessary steps to make attacks more difficult to succeed, like regularly updating software systems, securing applications, updating policies, applying patches, whitelisting and blacklisting.
Monitoring should run 24/7, as abnormalities or suspicious activity can occur any time of the day. A SOC monitoring around the clock can be immediately notified, which gives them the opportunity to respond immediately to incidents. Some organisations deploy monitoring tools such as an EDR and most include a SIEM, both of which have the capabilities to help analyse the difference between normal operations and threat-like behaviour.
The SOC is responsible for looking closely at each alert that comes from the monitoring tools. This gives them the opportunity to properly triage threats.
A company needs the least amount of network downtime to maintain operations. The SOC notifies the company of any security breach that could affect the network.
The SOC acts as a first-responder when there has been a security incident. They can perform actions like isolating endpoints, terminating harmful processes, preventing processes from executing and deleting files. Ideally, the SOC ensures that the security incident causes the least amount of downtime possible.
The SOC will work to restore systems and recover anything that has been lost. Part of this process may include restarting endpoints, wiping endpoints, deploying backups or reconfiguring systems.
The SOC collects and reviews logs of all network activity for the entirety of an organisation. The logs contain data that can indicate a baseline for normal network activity and what could be indicative of a threat; such data also assists in forensics during the aftermath of an incident.
Post-incident, it is the responsibility of the SOC to research the root cause of a security incident. They can use log data to find a possible source or identify an anomaly, at which point preventative measures can be applied.
Proper security measures require constant vigilance, which includes refinement and improvement of security measures. Plans that are outlined in a security road map are applied and refinements are constantly added to the road map to improve measures against cyber criminals, who are also always refining their methods.
SOCs are necessary for fighting against cyberattacks, which can significantly damage a company.
A SOC team leverages a centralised system for monitoring a company’s security, which means that all software and processes are stored in one place for smoother operations.
Customers expect organisations to take security seriously and protect their data. One incident can be enough to lose a customer, which is why a SOC team helps monitor and prevent attacks before they can infiltrate an organisation.
Security breaches may lead to significant losses in business reputation and revenue, which can dramatically alter an ROI and company’s bottom line. Firms save money that they would otherwise lose in recoveries and lost revenue from network downtime.
SOC’s presence for several years has yielded a series of best practices.
A SOC monitors network activity 24/7, which allows for rapid incident response. The moment a threat is detected, the SOC team should respond at an accelerated rate to ensure that the threat is neutralised before it can contribute to any downtime or result in the loss of data or privacy.
Machine Learning systems have the capabilities to monitor logs and watch traffic flows—they function on a trained algorithm that is meant to detect anomalies and immediately report suspicious activity. This can save time and allow security practitioners to focus on patterns and anomalies and work more efficiently.
The cloud has made cyber security more tricky, as a series of interconnected devices have created a wider surface area for cyberattackers to penetrate a firewall. All connections of the cloud infrastructure should be analysed to identify where threats and vulnerabilities could be located.
Cybercriminals are becoming more and more innovative in their attack methods. Cybersecurity teams also need to take an innovative and creative approach to preventative plans in anticipation of ever-evolving threats.
There are many tools available to SOC practitioners. There are basic tools like firewalls and intrusion detection systems, and foundational tools such as SIEMs. But more advanced tools are beginning to emerge, which will increase efficiency and accuracy. For example, tools that can analyse activity over the entire perimeter and reveal multiple points of entry that a hacker can target.
It is essential for an organisation to safeguard its data and assets. A SOC can protect a network and ensure that an organisation is less vulnerable to attacks, which provides peace of mind for customers and employees.
All network traffic from both internal and external sources, including servers, databases and routers.
A network operations center (NOC) focuses on monitoring the uptime of a network rather than cyber security threats.
Security information and event management (SIEM) is a network monitoring solution, providing alerts and network usage benchmarks for SOC teams to leverage.
Identify, prioritise, and respond to threats faster.
