What is Cyber Security?

Cyber security secures computers, servers, networks, and data from malicious attacks or illegal access. It is also the process of recovering computers and networks after an attack. As human society moves increasingly digital, threat actors have a greater incentive than ever to breach computer systems. These threats can be for financial gain, extortion, political or social motives (known as hacktivism), and even vandalism.


Cyber security is a collection of technologies, processes, and practices that protect computer networks, programs, and data from attack. It is also referred to as information technology security (ITS).

Cybersecurity professionals use various strategies to prevent and detect cyber attacks. Their responsibilities include:

  • Developing and implementing policies, strategies, and procedures.
  • Training corporate employees to protect their computers and sensitive data from hackers.
  • Assessing the impact of cyberattacks.

Installing a firewall and antivirus software is a common way to avoid cyber attacks. These tools help prevent malware, phishing attacks, spyware, and other threats that can disrupt the functioning of computer systems and devices.

Malware, which is malicious software, can be used to gain control of computer systems and steal sensitive data. Other forms of malware include ransomware, worms, Trojans, and spyware. Social engineering is another threat that involves tricking users into breaking their security procedures to obtain information.

What are the Goals of Cybersecurity?

Cyber security prevents unauthorized access, use, disclosure, interception, or destruction of electronic information and systems. It includes computer systems, networks, mobile devices, and other devices that contain data or information.

The goals of cyber security are confidentiality, integrity, and availability. These three pillars are called the CIA triad and guide information security policies in an organization.

Confidentiality measures ensure that information remains private and is only accessible to authorized parties. Integrity measures ensure that data is consistent, accurate, and trustworthy. Availability measures ensure data is available even if a component fails or a system crashes.

To achieve these goals, organizations can create a security operations center (SOC), which combines tools and human expertise to monitor, analyze, respond to, and recover from cybersecurity threats or vulnerabilities. This centralized base enables teams to quickly detect incidents and investigate their causes, ensuring that security measures are effectively implemented. These efforts improve efficiency, reduce complexity, and enhance visibility into systems and data.

What are the Risks of Cybersecurity?

Cyber security risks can impact your business in many ways, from customer trust to loss of market share. These threats can also damage the reputation, cause business disruptions, and violate compliance obligations.

Modern attacks are becoming more sophisticated. They require extensive knowledge of various technologies, configurations, and environments.

Attackers use phishing, social engineering, and other tactics to steal user logins, credit card credentials, and other personal information. They also use privilege escalation to expand their access and control to sensitive systems.

Hackers also use software supply chain attacks to exploit weak links in an organization’s trusted software update and supply chain. This can occur when an attacker uses a malicious version of an application or when they gain control of a third-party vendor’s database to spoof updates and patches.

What are the Strategies for Cybersecurity?

Cybersecurity strategies are a critical part of protecting a business from online threats. They should be created and regularly reevaluated to align with the current threat landscape.

Cybersecurity strategy outlines how a business will secure its data and information to combat cyber threats proactively. It also helps organizations to protect their proprietary information, sensitive data, and reputation.

As businesses become increasingly dependent on cloud services, a strong cybersecurity strategy is becoming more critical than ever. It protects organizations’ data, software, and hardware from malicious actors while remaining resilient in a cyberattack.

Creating a cybersecurity strategy can be challenging; it requires resources, management, and a complex technology stack. It also needs to be integrated.
