What is Cyber Security?

Cyber security refers to the practice of protecting computer systems, networks, and data from digital attacks, theft, or damage. As our world becomes increasingly interconnected through the internet, the importance of cyber security has grown exponentially. Cyber threats can take various forms, including hacking, malware, phishing, ransom ware, and other malicious activities.

Key Aspects of Cyber Security:

i.                    Network Security: Involves securing computer networks and infrastructure from unauthorized access, attacks, and disruptions.

xi.                 Security Auditing and Monitoring: Regularly reviews and monitors systems and networks to identify and address potential security issues.

xii.               Collaboration and Information Sharing: Involves cooperation and communication between organizations, government agencies, and the cyber security community to share threat intelligence and best practices.

As technology evolves, so do cyber threats, making cyber security an ongoing and dynamic field. Organizations and individuals need to stay vigilant, update their security measures, and adapt to emerging threats to maintain a strong defense against cyber-attacks.



Cyber security threats are diverse and constantly evolving as technology advances. Here are some common cyber security threats that organizations and individuals may face:

i.                    Malware: Malicious software, such as viruses, worms, Trojans, and ransom ware, designed to disrupt, damage, or gain unauthorized access to computer systems.

ii.                  Phishing: A type of social engineering attack where attackers use deceptive emails, messages, or websites to trick individuals into providing sensitive information, such as login credentials or financial details.

iii.                Denial of Service (DoS) and Distributed Denial of Service (DDoS) Attacks: These attacks aim to overwhelm a network, system, or website with a flood of traffic, rendering it unavailable to users.

iv.                 Man-in-the-Middle (MitM) Attacks: Involves intercepting and potentially altering communication between two parties without their knowledge, compromising the confidentiality and integrity of the data.

v.                   SQL Injection: Exploits vulnerabilities in web applications to manipulate a database by injecting malicious SQL code.

vi.                 Cross-Site Scripting (XSS): Injecting malicious scripts into web pages that are viewed by other users, compromising their data or session information.

vii.               Zero-Day Exploits: Attacks that target vulnerabilities in software or hardware that are not yet known to the vendor or for which no patch is available.

viii.             Insider Threats: Security risks that arise from individuals within an organization, such as employees or contractors, who misuse their access and privileges to intentionally or unintentionally harm the organization.

ix.                 Password Attacks: Techniques like brute force attacks, password spraying, and credential stuffing to gain unauthorized access to accounts by exploiting weak or compromised passwords.

x.                   IoT (Internet of Things) Vulnerabilities: Insecure IoT devices can be exploited to gain unauthorized access to networks or launch attacks.

xi.                 Eavesdropping (Sniffing): Unauthorized interception of network traffic to gather sensitive information, such as login credentials or financial data.

xii.               Social Engineering: Manipulating individuals into divulging confidential information or performing actions that may compromise security.

xiii.             Fileless Malware: Malicious code that operates in memory rather than on a computer's file system, making it harder to detect by traditional antivirus software.

xiv.             Crypto-jacking: Illicit use of a computer's resources to mine crypto-currencies without the owner's knowledge or consent.

xv.               Misconfigured Security Settings: Failing to configure security settings properly, leaving systems and networks vulnerable to exploitation.

It's essential for organizations and individuals to stay informed about these threats, implement security best practices, and regularly update their cyber security defenses to mitigate the risks associated with evolving cyber threats.
