00:00 — Welcome to IRA

Welcome to IRA Intellix Academy. In this introductory lesson, we explore Cyber Security. Notice the signal. Respond with purpose. You will learn the basic ideas, follow a practical example, and try a small task yourself. Keep a notebook nearby. The example uses fictional information for learning. Our goal is to understand the decisions behind the work, so you can explain both what you would do and why.

00:30 — Threats, vulnerabilities and risk

Cyber security begins with understanding what could go wrong and why it matters. A threat is a possible source of harm. A vulnerability is a weakness that could be exploited. Risk considers the likelihood and impact of an unwanted event in a particular context. These ideas are connected, but they are not interchangeable. An account with a weak sign-in process may have a vulnerability. Someone attempting to misuse it represents a threat. The risk depends on what the account can access and how likely misuse is. Start by identifying valuable information and essential services, then consider appropriate protections and response procedures.

01:30 — Protection, detection and response

No single control solves every security problem. Prevention reduces opportunities for harm. Detection helps notice suspicious activity. Response helps limit the impact when something happens. Secure configuration and appropriate access are examples of preventive controls. Activity logs and alerts support detection. An incident playbook supports a consistent response. These controls also depend on people understanding their responsibilities. A warning that nobody reviews has limited value. A response action without an owner can be delayed. When reviewing a security process, ask what it protects, how a problem becomes visible, who investigates it, and what evidence supports the next decision.

02:30 — A suspicious sign-in alert

Consider a fictional employee who receives an unexpected sign-in alert. The event shows an unfamiliar location and device. It deserves attention, but it does not prove that an attacker accessed the account. Travel, network routing, and legitimate device changes can affect the context. Begin with the available evidence. Record the event time, account, source, relevant device information, and the alert message. Preserve the original information rather than rewriting it from memory. Contact the employee using a trusted channel. Avoid relying on a reply to a suspicious message. The investigation should establish what happened before selecting a proportionate response.

03:30 — Step one: build an event timeline

Build a timeline from relevant account activity. Was the sign-in successful or only attempted? Did the authentication challenge complete? Were there changes to recovery details, forwarding rules, or access permissions? Which facts are confirmed, and which are assumptions? Write these separately. Correlate records using consistent times and identify any timezone differences. A clear timeline makes it easier for another responder to follow your reasoning. Limit your review to systems and data you are authorised to investigate. If essential evidence is missing, record that gap and escalate through the established process rather than inventing an explanation to complete the report.

04:30 — Step two: contain confirmed misuse

If the investigation confirms unauthorised access, follow the organisation's containment procedure. An authorised responder may revoke affected sessions, secure the account, and restrict access while assessing the incident. The exact actions depend on the service, evidence, and business impact. Avoid making uncontrolled changes that destroy useful records or disrupt unrelated users. Communicate who is responsible for each action and when it was performed. Also ask whether the affected account reached other systems or shared resources. Containment is about limiting further harm while preserving enough evidence to understand the event. A documented, proportionate response is more useful than a series of improvised clicks.

05:30 — Step three: recover and monitor

Recovery means returning the account or service to an acceptable state and checking that the issue has been addressed. Review suspicious changes, restore authorised settings, and confirm that the legitimate user can work safely. Where policy requires it, reset affected credentials and review authentication methods through approved channels. Continue monitoring for related activity rather than assuming the problem ended with one action. Keep the account owner informed using clear, practical instructions. Do not ask them to send passwords or verification codes in ordinary messages. Finally, record what was restored, what was verified, and which follow-up checks remain open.

06:30 — Write a useful incident report

A useful incident report helps someone understand the event without guessing. Summarise the issue, affected assets, confirmed impact, evidence, response actions, and current status. Include a timeline and identify unresolved questions. Separate observations from interpretations. For example, three failed sign-in attempts is an observation; an attacker definitely stole data is a claim that needs evidence. Use precise language and avoid dramatic labels. The report should also support improvement. Could an alert be clearer? Was the response owner obvious? Did an outdated contact list slow the investigation? Learning from the event strengthens the process beyond the single account involved.

07:30 — Your incident-triage exercise

Your task is to triage the fictional alert. Write three questions you would ask before concluding that the account was compromised. Name two sources of relevant evidence. Then describe one containment action that an authorised responder might take if misuse is confirmed. Pause and check that your answer does not jump from an unfamiliar location directly to a definite conclusion. A strong response checks event success, authentication context, user activity, and subsequent changes. Finish with a short report that labels unknowns clearly. This exercise develops a valuable security habit: investigate with evidence, act within your authority, and explain the reasons for your decisions.
