1. Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, typically covertly, so that the person using the keyboard is unaware that their actions are being monitored. Explain a situation where using a keyloggers may be used in either a legitimate (legal) way or used as a tool for criminals.

Keystroke logging can be used legitimately in various scenarios, such as corporate investigations to monitor employee activity for security purposes, ensuring compliance with company policies, or tracking the use of company devices to prevent data leaks. For example, an IT security team may deploy keyloggers to detect suspicious activities or insider threats within the organization. Conversely, cybercriminals often use keylogging malware to secretly capture sensitive information like passwords, credit card numbers, or personal data with malicious intent, leading to identity theft or financial fraud.

2. System Breach Case Study

One notable system breach involved the attack on Target Corporation in 2013. During this incident, hackers compromised Target’s point-of-sale (POS) systems, resulting in a massive data breach. The attackers gained access to sensitive customer data, including names, credit and debit card numbers, expiration dates, and CVV codes. It was estimated that around 110 million customers' financial information was compromised, making it one of the largest retail breaches at the time. The breach was traced back to malware installed on Target’s POS terminals, which stole payment card data during transactions.

The breach was discovered approximately two weeks after the initial intrusion, highlighting the delay often involved in identifying such security incidents. The investigation revealed that the breach had been ongoing since mid-November 2013, but it was only publicly disclosed in December 2013. The breach not only resulted in significant financial losses for Target but also damaged its reputation and customer trust. The incident underscored the importance of robust cybersecurity controls and timely incident detection mechanisms.

3. Recovering IT Resources from Disasters and Preventative Controls

Organizations can recover their IT resources from a disaster by implementing comprehensive disaster recovery (DR) plans, which include regular data backups, disaster recovery sites, and clear recovery procedures. Key steps involve restoring data from backed-up copies, maintaining redundant hardware or cloud infrastructure to ensure business continuity, and systematically verifying the integrity of recovered data. Additionally, organizations should perform regular testing of recovery processes to identify and address gaps before an actual disaster occurs.

Preventative controls are vital to minimize the risk of disaster occurrence and facilitate recovery. These controls include deploying firewalls, intrusion detection and prevention systems, encryption for sensitive data both at rest and in transit, and strict access controls to reduce the likelihood of cyberattacks. Also, maintaining updated security patches on all systems reduces vulnerabilities that could be exploited by attackers. Implementing an incident response plan that clearly defines roles and responsibilities ensures swift action when a breach or disaster happens, reducing downtime and data loss.
