The importance of cyber security
Cyber security is a very important thing for military, corporate, government, financial, and medical organizations. Because, they collect, operate and store many sensitive data/information on computers and other devices that they need. What cyber security does is, It explains how to transmit your data using the network safely and how you need to store it securely.
There are four major areas in Cyber security
- Network Security
- Application Security
- Information security
- Disaster Recovery
- Critical Infrastructure Security
- Cloud security
1. Network Security
This is for preventing and protecting against unauthorized intrusion or attackers into computer networks.
2. Application Security
Application Security enhances and protects the softwares and devices from external threats.
3. Information Security
Information security is organized to secure the confidentiality, integrity and availability of computer system data from unauthorized access or alterations
4. Disaster Recovery
Disaster recovery involves and aims on the IT systems for supporting when the organization or company faces a natural or human-induced disaster.
5. Critical infrastructure security
This belongs to cyber-physical systems such as electricity grid and water purification systems
6. Cloud Security
These are kind of software based tools that protect and enhance your data security in the cloud, this helps to eliminate the risks associated with on-premises attacks.
Types of cyber threats
There are three types of cyber threats,
Cybercrime is any kind of criminal activity that impacts(hacking, phishing, spamming) a computer, networked device or a network for a financial gain or to cause disruption.
Cyber-attack often works for gathering politically motivated information.
Cyberterrorism is the activity that can be used through the Internet to conduct violence and as a results, threaten and cause loss of life or significant bodily damage.

What are the challenges in cybersecurity?
Cybersecurity is continually challenged by hackers, data loss, privacy, risk management, and changing cybersecurity strategies. Nothing currently indicates that cyber-attacks will decrease. Moreover, with the more entry points, there are for attacks, the more cybersecurity is needed to secure networks and devices.
Cybersecurity is always challenged by hackers. So we need to protect and secure the networks and devices.
One of the most critical elements of cybersecurity is, continually evolving nature of security risks.
There are three commonly known cybersecurity vendors. They are Cisco, McAfee and Trend Micro.
Cisco basically focuses on networks and allows their customers to utilize firewalls, VPNs and advanced malware protection systems for supporting email and endpoint security. They(Cisco) also support real-time malware blocking.
McAfee develops cybersecurity products for consumers and enterprise users. This is supportive for mobile, enterprise clouds, network, web and server-based security. McAfee offers data protection and encryption.
Trend Micro is an anti-malware vendor which offers threat protection services for mobile, hybrid clouds, SaaS and the IoT.
Most Common Sources of Cyber Threats
- Nation states or national governments
- Industrial spies
- Organized crime groups
- Hacktivists and hackers
- Business competitors
- Disgruntled insiders
