More about a career in Vulnerability Management

If you're passionate about IT security, then working in vulnerability management is an interesting and essential role in any organisation. You might work as a solo practitioner or as part of a larger vulnerability management or cyber security team. 

At a junior level, you probably work under supervision, assisting the team in looking for potential vulnerabilities in the organisation's systems. You use your investigative and analytical skills to the full, growing your expertise and expanding your knowledge at the same time. There may be opportunities to be involved with many projects, programmes and initiatives across your organisation, as well as within the cyber team itself. 

As a more experienced practitioner, you conduct and interpret vulnerability scans. You're probably involved with the team responding to security incidents, working out the root causes of incidents and collating the lessons learned. You drive fundamental change within the organisation by helping to develop security initiatives; this may include briefing and educating other teams within the organisation on vulnerabilities and solutions to them, or mentoring junior team members. 

You may be responsible for providing reports to clients on their systems’ vulnerabilities, turning technical analysis into something that non-technical readers can understand.

Overall, you will help protect information systems and assets by identifying and closing off vulnerabilities in devices, systems and networks.

In detail, you might:

  • stay up to date with reports of vulnerabilities in ff-the-shelf software and hardware
  • research potential vulnerabilities in the organisation’s systems
  • identify and prioritise vulnerabilities
  • propose and implement mitigations for identified vulnerabilities
  • work on different projects such as patch compliance and sector-specific compliance (for example, with PCI-DSS standards)
  • work with our internal and external Certifying Authorities (CA)
  • configure ADFS and remote access solutions
  • run network and application vulnerability scans
  • provide support to and work directly with clients on vulnerabilities
  • write and deliver client reports

Some organisations have a dedicated cyber security team and, depending on the organisation's size, may have a threat/vulnerabilities management team within that.  Smaller organisations may have only one more experienced individual to look after all their cyber security requirements, including Vulnerability Management.

A practitioner:

  • is likely to be part of a team of mixed cyber security specialists
  • assists with tracking and assessing vulnerabilities and managing the closure of vulnerabilities which create risks for the organisation 

A senior practitioner:

  • provides information and advice to other specialist and internal/external teams, generating awareness of cyber vulnerabilities and their solutions
  • helps, as a team leader, provide career development and guidance to junior analysts 

Personal attributes

  • an inquisitive nature and a problem-solving approach
  • prioritises work and escalates issues appropriately
  • interpersonal skills enabling effective interaction with technical and non-technical teams
  • verbal and written communication skills
  • evaluating the probable social, commercial, cultural, ethical and environmental consequences of an action

Specialist skills

  • interpreting, analysing, and reporting information/data security events and anomalies in accordance with Information Security directives
  • assessing new vulnerabilities, investigating solutions, and recommending controls to minimise risks that could arise
  • operating network intrusion detection, forensics, network access control, and other information security systems
  • troubleshooting and resolving failed patch installations and SCCM automation jobs
  • configuring and troubleshooting networks
  • using network and application scanning tools and utilities, such as SCCM, Nexpose Rapid 7, HP WebInspect, HCL AppScan, Nessus, Burp Suite and NMAP
  • configuring encryption protocols and algorithms
  • onboarding and decommissioning devices
  • maintaining an asset database

Coming soon

Any role in which you carry out research, closely analyse a situation or event, and share findings with colleagues may provide a foundation, with additional specialist training, for moving into Vulnerability Management. 

Such roles include:

  • police services: detection and intelligence roles
  • military services: intelligence analysts
  • business assurance
  • communications engineers

Working in a cyber security role requires specialist knowledge, and some roles require a lot. Such knowledge can be acquired in several ways and, although the requirements for any given role are described here in terms of Knowledge Areas (KAs) from the Cyber Security Body of Knowledge (CyBOK), this doesn't mean that a cyber security specialist must read the relevant sections of CyBOK.

Increasingly, however, cyber security qualifications, training and skills definitions are being mapped to CyBOK - so the KAs are a good way of describing the knowledge associated with a specialism.

As an experienced practitioner in a Vulnerability Management role, you'll typically use the knowledge in the KAs listed below, although not always to the same level of detail. You're most likely to have a very good understanding of the Core Knowledge, which is essential to performing the role. You may still need a good understanding of the Related Knowledge but not to quite the same degree. You may need much less detailed understanding of the elements of Wider Knowledge, which provides context for your work.

Coming into such a role, you will not be expected to have all his knowledge initially.

Core knowledge

Security Operations & Incident Management 

The configuration, operation and maintenance of secure systems including the detection of and response to security incidents and the collection and use of threat intelligence.

Web & Mobile Security
