What does a Cyber Security Analyst do?

Protecting your data, safeguarding your future – the digital guardians against cyber threats. This role is vital in ensuring the safety and integrity of an organisation’s information systems.

Most organisations now recognise that the importance of safeguarding information from cyber threats cannot be overstated. The impact of cyber security attacks can be catastrophic, with far-reaching consequences for organisations. A quick search for “cyber attacks in history” reveals numerous high-profile cases where cyber defences failed, leading to significant damage. These incidents highlight the critical need to protect sensitive data from malicious attacks.  

At the heart of this effort is the Cyber Security Analyst. This role is vital in ensuring the safety and integrity of an organization’s information systems. But what exactly does a Cyber Security Analyst do, and why is this role so crucial for organisations?

A Cyber Security Analyst is a professional tasked with protecting an organisation's computer systems and networks from cyber threats. Their primary role involves monitoring, detecting, and responding to security incidents to ensure that sensitive information remains secure from unauthorized access. For those new to the field, think of a Cyber Security Analyst as a digital guardian, constantly on the lookout for potential threats and vulnerabilities within an organisation's IT infrastructure. 

The role is essential because, in an era where data breaches and cyber-attacks are increasingly common, protecting confidential information is more critical than ever. Cyber Security Analysts help organisations avoid the potentially devastating consequences of these attacks, including financial loss, reputational damage, and legal penalties. They play a pivotal role in maintaining the trust and confidence of clients, partners, and stakeholders by ensuring that sensitive information is secure. 

As a Cyber Security Analyst, you could manage the security of the organisation you work for or offer security services and consultancy to other companies. 

An organization employs Internal Cyber Security Analysts directly to protect its digital infrastructure. They have an in-depth understanding of the company’s systems, policies, and culture. Their responsibilities as previously detailed, include continuously monitoring internal networks, implementing security measures, responding to incidents, and ensuring compliance with internal policies and regulations.  

External Cyber Security Analysts, on the other hand, work for third-party security firms or as independent consultants. They provide specialized expertise to multiple clients, often conducting security assessments, and audits. They offer a fresh perspective on security vulnerabilities and provide recommendations for improving an organization’s security posture. Outside analysts are sometimes brought in for certain projects or to handle security issues. However, they may not have the same level of familiarity with the company's internal systems as internal analysts do.

Exploring the Day-to-Day: A Detailed Example of an Incident Response.

Context: 

A medium-sized financial services company recently experienced a phishing attack targeting its employees. One of the employees inadvertently clicked on a malicious link in an email, leading to a compromise of their account.

Actions that were Taken by the Cybersecurity Analyst:

Initial Detection and Analysis: 

  • The cybersecurity analyst received an alert from the company’s intrusion detection system (IDS) about unusual login activity from the compromised account.
  • The analyst quickly reviewed the logs and identified the phishing email that led to the compromise. 

Containment:

  • The analyst immediately isolated the compromised account to prevent further unauthorized access.
  • They informed the affected employee and guided them to disconnect their device from the network. 

Eradication: 

  • The analyst performed a thorough scan of the compromised device to remove any malware.
  • They reset the affected account’s password and enforced multi-factor authentication (MFA) to enhance security. 

Recovery: 

  • The compromised account was restored with new security measures in place.
  • The analyst ensured that no sensitive information was exfiltrated by reviewing data access logs. 

Post-Incident Activities: 

  • The analyst conducted a root cause analysis to understand how the phishing email bypassed the email security filters.
  • They updated the email filtering rules and implemented additional anti-phishing measures, such as stronger email authentication protocols. 

Education and Training: 

  • The analyst organised an emergency training session for all employees to highlight the dangers of phishing attacks and teach them how to recognise suspicious emails.
  • They provided tips on safe email practices and reinforced the importance of reporting suspicious activity. 

Reporting and Documentation: 

  • The analyst documented the incident, the steps taken to mitigate it, and the lessons learned.
  • They presented a report to the management team, outlining the impact of the incident and the improvements made to the security posture. 

Outcome: 

  • Thanks to the swift actions of the cybersecurity analyst, the phishing attack was contained with minimal impact. The company strengthened its defences against future attacks, and employees became more vigilant about potential phishing threats. 

This example illustrates the multifaceted role of a cybersecurity analyst, encompassing detection, response, mitigation, and education to protect an organisation’s digital assets.
