"In a connected world, security is not an option — it's a necessity."
Learn MoreCybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes.
In our increasingly connected world, everyone benefits from advanced cyberdefense programs. At an individual level, a cybersecurity attack can result in everything from identity theft to extortion attempts, to the loss of important data like family photos. Everyone relies on critical infrastructure like power plants, hospitals, and financial service companies.
Cybersecurity is a fundamental pillar in the field of network engineering. As networks become more complex and interconnected, the need for robust security measures becomes critical. Network professionals must understand both the technical infrastructure and the security protocols needed to protect valuable digital assets.

Understanding the threats is the first step to protection
Fraudulent attempts to obtain sensitive information by disguising as a trustworthy entity in electronic communications. Attackers often use fake emails or websites.
Malicious software designed to block access to a computer system until a sum of money is paid. It encrypts files and demands payment for the decryption key.
Software intentionally designed to cause damage to a computer, server, client, or network. Includes viruses, trojans, worms, and spyware.
A security incident in which sensitive, protected, or confidential data is accessed or disclosed without authorization. Can result in massive data leaks.
A trial-and-error method used to obtain information such as passwords or Personal Identification Numbers (PINs) by systematically checking all possible combinations.
Psychological manipulation of people into performing actions or divulging confidential information. Exploits human trust rather than technical vulnerabilities.
Essential steps to protect yourself and your organization
Use complex passwords with a minimum of 12 characters, including uppercase and lowercase letters, numbers, and special symbols. Never reuse passwords across different accounts.
Enable 2FA on all accounts that support it. This adds an extra layer of security by requiring a second form of verification beyond your password.
Encrypt sensitive data both at rest and in transit. Use end-to-end encryption for communications and full-disk encryption for devices.
Implement the 3-2-1 backup rule: 3 copies of data, on 2 different media types, with 1 copy offsite. Automate backups and test restoration regularly.
Keep all software, operating systems, and applications up to date. Enable automatic updates when possible to patch security vulnerabilities quickly.
Stay informed about the latest security threats and trends. Educate yourself and others about recognizing and avoiding common attack vectors.
Essential cybersecurity terminology
A network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
A secure connection between a device and a network that encrypts data and hides the user's IP address.
An authorized simulated cyber attack on a computer system to evaluate its security and identify vulnerabilities.
A cyber attack that occurs on the same day a weakness is discovered in software, before a patch is available.
Distributed Denial of Service - an attempt to make an online service unavailable by overwhelming it with traffic.
Secure Sockets Layer/Transport Layer Security - protocols for establishing authenticated and encrypted links.
A device or software that monitors a network for malicious activity or policy violations.
The practice of securing endpoints or entry points of end-user devices from being exploited by malicious actors.
The process of verifying the identity of a user, process, or device as a prerequisite to granting access.
The process of distributing and applying updates to software to fix vulnerabilities and improve functionality.
An ethical hacker who uses their skills to improve security by finding vulnerabilities legally and ethically.
A physical or digital device used to authenticate a user's identity electronically in two-factor authentication.
