A cybersecurity expert is someone who has the knowledge and skill set to detect, respond to and prevent cyberattacks. Their work isn’t limited to businesses, but they work for governments or other organisations to keep their systems secure. A cybersecurity expert works on identifying possible system vulnerabilities before cyber attackers strike their systems.

A cybersecurity expert works proactively by conducting vigilant scans for suspicious activity. If they encounter such activity, they immediately employ countermeasures to ensure the safety of their networks and prevent further damage. In their work, cybersecurity experts protect all tasks involving sensitive information, such as sending, receiving, logging in, or sharing. A cybersecurity expert helps protect data at rest and during transit.

A cybersecurity expert’s job includes more than keeping a watchful eye on cybersecurity systems. They must adopt a proactive approach to cybersecurity, continuously looking for possible vulnerabilities and suggesting and enforcing possible protective measures. They are responsible for implementing the organisation’s cybersecurity action plan if it is under attack and propose possible modifications to its cybersecurity measures to stay updated with the latest cybersecurity threats.

Identifying and Assessing Risks

A cybersecurity expert’s main job requirement is identifying and assessing cybersecurity risks. A cybersecurity expert must be able to pinpoint possible system and network vulnerabilities and understand what methods cyber attackers might use to infiltrate the organisation. There are several steps they must take to achieve and serve their organisation’s cybersecurity goals properly. These three steps are:

Understanding the Organisation

Properly serving the organisation’s cybersecurity goals entails mapping its IT infrastructure, including all hardware, software, networks and devices. The following step is to identify all valuable data assets and their sensitivity levels to determine the proper protection measures to adopt. Then, a cybersecurity expert must analyse how users access and interact with the organisation’s and outside systems to determine the level of protection measures needed.

Threat Landscape Analysis

After a cybersecurity expert has completed an initial and comprehensive analysis of the organisation, they must stay informed about current cyber threats and attacker tactics relevant to the organisation’s industry and size. This comprehensive understanding allows them to properly assess the possible impact of different types of attacks, such as phishing, malware or ransomware, on the organisation.

Vulnerability Assessment

The final risk identification and assessment step is identifying the organisation’s cybersecurity vulnerabilities. A cybersecurity expert can test security systems and applications for possible exploitable weaknesses by cyber attackers. They must also continuously evaluate existing security controls for effectiveness, identify potential security gaps, and prioritise risks based on severity and exploitability.

Implementing Security Controls

Cybersecurity experts have numerous tools to employ and techniques to implement to ensure the safety of the organisation’s cybersecurity realm and mitigate the effects of any cybersecurity attack. We can conclude these tools in the following categories.

Layered Defense Approach

Generally, it’s best if cybersecurity experts adopt a layered defence approach. This approach effectively keeps cyber attackers at bay and gives cybersecurity experts enough time to detect and respond to the attack. The defence layers include different IT levels such as network, endpoint, application and data layers. The tools a cybersecurity expert can use to secure these layers include deploying firewalls, intrusion detection and prevention systems, antivirus and antimalware agents and data encryption tools.

Access Control

A vital cybersecurity step is enforcing a least privilege policy. This policy limits who has access to information, where users only have access to the data and resources they need for their job. Implementing strong authentication and authorisation mechanisms also ensures the protection of the identity and information of the users with access to information.

Configuration Management

A cybersecurity expert must ensure all systems and devices are properly configured with secure settings and up-to-date software patches. These two categories represent the most exploitable cybersecurity vulnerabilities cyber attackers use to access systems. Proper data backup ensures the organisation can return immediately after any breach or attack.

Incident Response Planning

A cybersecurity action plan is a joint responsibility of the cybersecurity experts and the organisation’s management. The expert must develop a clear and well-defined plan for responding to security incidents and include roles and responsibilities for all stakeholders. After the forging of such an action plan, the cybersecurity expert must adequately explain it to the employees and define their roles in protecting their organisation’s system.

Monitoring and Analysing Security Events

These experts need to be able to monitor systems for signs of an attack. They must continuously monitor system logs for suspicious activity, such as failed login attempts, unauthorised access attempts or unusual data transfers. A cybersecurity expert will utilise SIEM (Security Information and Event Management) tools to aggregate and analyse data from various security sources for centralised monitoring and threat detection.

Vulnerability scans are another method cybersecurity experts use to monitor and analyse security events. They regularly scan systems for vulnerabilities and prioritise remediation efforts based on critical vulnerabilities. These experts must stay updated on current threats and attack patterns to improve detection and response capabilities.

Responding to Security Incidents

If a cybersecurity attack occurs, cybersecurity experts need to be able to respond swiftly and effectively to contain the damage and prevent further attacks. They must follow the action plan steps to quickly isolate the affected systems and data to prevent further damage or compromise and deactivate compromised accounts or devices. As they work to contain the cybersecurity attack, cybersecurity experts determine the incident’s scope and impact, identify the root cause and gather evidence about the source of the attack or vulnerability.

After identifying the root cause, a cybersecurity expert eradicates malware or other malicious software from affected systems. Then, they work to restore affected systems and data to normal operation so the organisation can return to its daily tasks. The final step is to document the incident, notify relevant stakeholders and communicate lessons learned with other employees to prevent future occurrences.

Educating and Training Users

The cybersecurity landscape constantly changes, so cybersecurity experts must stay updated on the newest threats and trends. When cybersecurity experts learn new protection measures, they should transfer such knowledge to other employees. They can conduct regular training sessions on cyber threats, phishing scams, social engineering techniques and best practices for password hygiene and secure data handling.

Another possible educative method is conducting simulated phishing attacks or cyber incidents to test user awareness and the effectiveness of security controls. A cybersecurity expert will work on developing and disseminating clear security policies and procedures for all employees to follow as part of a cybersecurity action plan.
