America's first national cybersecurity policy, National Security Decision Directives or NSDD 145, was implemented on September 17, 1984, inspired by the WarGames movie.

This policy outlined a comprehensive directive to protect national communications and information systems.

A notable surge in cyberattacks following 9/11 prompted the US government to initiate several cybersecurity measures, including establishing the Department of Homeland Security (DHS) and the National Cyber Security Division (NCSD).

A collaborative effort involving a proactive cybersecurity community, an alert public, and organizations investing in cybersecurity infrastructure is consistently underway to safeguard our growing virtual presence, especially in the wake of the COVID-19 pandemic.

The history of cybersecurity dates back to the early 1970s when the first computer worm emerged. However, it has undergone substantial evolution over the years, with the increased dependence on digital technology.

Critical thinking forms the bedrock of effective cybersecurity, enabling professionals to make informed decisions, innovate, and anticipate threats.

This skill involves objectively analyzing information and forming reasoned judgments.

You can employ critical thinking in cybersecurity to:

o Evaluate online information

o Engage in productive discussions

o Consider ethical aspects

o Navigate complex obstacles

o Perform root cause analysis

o Embrace new technologies

o Pursue lifelong learning

The critical thinking model, which offers a holistic approach to addressing cybersecurity challenges, comprises five key elements:

o Characteristics of thought

o Technical skills

o Interpersonal skills

o Theoretical and experimental knowledge

o Intellectual abilities

Similarly, five pivotal critical thinking skills help form the foundation of critical thinking in every professional field, including cybersecurity:

o Challenge assumptions

o Consider alternatives

o Evaluate data

o Identify key drivers

o Understand the context

Network mapping is the process of understanding and visualizing a network’s physical and logical connections. It serves as a valuable tool for IT and cybersecurity professionals to manage networks effectively, but attackers also exploit this method to their advantage.

Packet sniffing is a technique involving the use of software to capture and analyze data packets as they traverse a network. IT professionals employ it for network troubleshooting, performance monitoring, and activity oversight, whereas attackers use it to steal sensitive information.

IP spoofing involves manipulating packet headers to alter the source address, effectively concealing the true origin of the sender or pretending to be another host.

A denial of service (DoS) attack is a malicious attempt to disrupt the normal functioning of a targeted server, service, or network by overwhelming it with a flood of illegitimate traffic or requests.

Injection attacks are cyberattacks where an attacker injects malicious code into a query, web application, or system, triggering remote commands that manipulate website data. It has two variants - SQL injection and XSS.

Security controls are essential for safeguarding the confidentiality, integrity, and availability of critical information and other crucial assets from potential threats. Some of these include administrative, physical, and technical controls.

IT professionals actively implement a variety of methods and tools to maintain system security. These include access controls, encryption, patching, regular backups, system-level firewalls, and antivirus software.

Network security protects networking infrastructure from unauthorized access, exploitation, or theft. Its primary objectives include preventing unauthorized access, detecting and stopping cyber threats, and facilitating secure access for legitimate users.

Application security involves incorporating a series of secure practices and processes into every phase of the software creation process.

Organizations must incorporate vulnerability management into their cybersecurity strategy as it identifies, assesses, and mitigates weak points. These programs spot security gaps and triage the most critical issues by performing routine vulnerability scans.

The National Institute of Standards and Technology, or NIST, is renowned for establishing industry standards. The NIST plan outlines four key phases of the incident response (IR) lifecycle. These are:

Preparation and planning

Detection and analysis

Containment, eradication, and recovery

Post-incident activities
