What is Cyber Security?

Cyber security consists of technologies, processes and controls designed to protect systems, networks, programs, devices and data from cyber attacks. Effective cyber security reduces the risk of cyber attacks and protects against the unauthorised exploitation of systems, networks and technologies.Cybersecurity is the protection of internet-connected systems, including hardware, software and data, from cyberattacks. In a computing context, security comprises cybersecurity and physical security — both are used by enterprises to protect against unauthorized access to data centers and other computerized systems. Information security, which is designed to maintain the confidentiality, integrity and availability of data, is a subset of cybersecurity.


Types of cybersecurity threats

The process of keeping up with new technologies, security trends and threat intelligence is a challenging task. However, it’s necessary in order to protect information and other assets from cyber threats, which take many forms.


  • Ransomware is a type of malware that involves an attacker locking the victim’s computer system files — typically through encryption — and demanding a payment to decrypt and unlock them.
  • Malware is any file or program used to harm a computer user, such as worms, computer viruses, Trojan horses and spyware.
  • Social engineering is an attack that relies on human interaction to trick users into breaking security procedures in order to gain sensitive information that is typically protected.
  • Phishing is a form of fraud where fraudulent emails are sent that resemble emails from reputable sources; however, the intention of these emails is to steal sensitive data, such as credit card or login information.

Elements of cyber security

Ensuring cybersecurity requires the coordination of efforts throughout an information system, which includes:


  • Application security
  • Information security
  • Network security
  • Disaster recoverybusiness continuity planning
  • Operational security
  • End-user education

One of the most problematic elements of cybersecurity is the continually evolving nature of security risks. The traditional approach has been to focus resources on crucial system components and protect against the biggest known threats, which meant leaving components undefended and not protecting systems against less dangerous risks.


Benefits of Cybersecurity

Benefits of utilizing cybersecurity includes:


  • Business protection against malware, ransomware, phishing and social engineering.
  • Protection for data and networks.
  • Prevention of unauthorized users.
  • Improves recovery time after a breach.
  • Protection for end-users.
  • Improved confidence in the product for both developers and customers.

Cybersecurity vendors

Vendors in cybersecurity fields will typically use endpoint, network and advanced threat protection security as well as data loss prevention. Three commonly known cybersecurity vendors include Cisco, McAfee and Trend Micro.Cisco tends to focus on networks and allows its customers to utilize firewalls,VPNs and advanced malware protection along with supporting email and endpoint security. Cisco also supports real-time malware blocking. McAfee makes cybersecurity products for consumers and enterprise users. McAfee supports mobile, enterprise clouds, network, web and server-based security. Data protection and encryption is also offered.  


Trend Micro is an anti-malware vendor which offers threat protection for mobile,hybrid clouds,SaaS and the IoT. Trend Micro provides users with endpoint, email and web security.


Cyber security checklist

Boost your cyber defences with these must-have security measures:


 

1. Staff awareness training

Human error is the leading cause of data breaches, so you need to equip staff with the knowledge to deal with the threats they face. Training courses will show staff how security threats affect them and help them apply best-practice advice to real-world situations.


 

2. Application security

Web application vulnerabilities are a common point of intrusion for cyber criminals. As applications play an increasingly critical role in business, it is vital to focus on web application security.


 

3. Network security

Network security is the process of protecting the usability and integrity of your network and data. This is achieved by conducting a network penetration test, which scans your network for vulnerabilities and security issues.


 

4. Leadership commitment

Leadership commitment is the key to cyber resilience. Without it, it is very difficult to establish or enforce effective processes. Top management must be prepared to invest in appropriate cyber security resources, such as awareness training.


 

5. Password management

Almost half of the UK population uses ‘password’, ‘123456’ or ‘qwerty’ as their password. You should implement a password management policy provides guidance to ensure staff create strong passwords and keep them secure.
