Disadvantages of Cyber Security

Let’s talk about the disadvantages now, which are as follows:

  1. Expensive task: Organisations have to buy certain digital securities to reduce or prevent cyber-attacks. This increases their expenditures, which becomes a difficult task in the case of small and medium businesses.
  2. Complications in handling: In today’s advanced cyber threats, it becomes a very complex task to manage all the peripherals of cyber attacks. Cyber security experts are required in such cases to avoid such damages.
  3. Difficulty for users: Cyber security involves frequent password changes and multiple-factor authentication, which does not make it user-friendly and sometimes, even reduces the productivity level.
  4. Ineffective against insider threats: Cyber security does not sound successful in case of insider attacks as these hackers have access to networks, systems and data and cyber security is sometimes unable to detect and prevent such insider attacks.
  5. Stabilising security and practice: A Strict cyber security system obstructs the user's security and productivity and enables them from finding a correct balance between the both.
  6. Retards working of the system: Stringent security measures consisting of multiple-factor authentications and multiple passwords make the whole system work slowly, thus consuming a lot of time and reducing the productivity of the person working on it.
  7. Continuous surveillance: Cyber security is not just a one-time thing, and thus, requires consistent cyber security monitoring and updations. It requires uninterrupted consideration and requires years of effort, study and experiments to build up a strong cybersecurity system.

Types of CyberSecurity

Cybersecurity is a crucial part of personal, professional, social, and working space, and so are the different types of cyber securities designed to secure data on various grounds. Let’s talk about these now.

  1. Application Security: It secures software applications from internet threats causing susceptibility.
  2. Network Security: Almost all of the cyber security threats occur through accessing the network and hence network security works on shielding the networks from unauthorised access.
  3. Cloud Security: Various cyber security companies use cloud computing to store their data and applications. Hence, cloud security performs a vital function in securing the cloud’s information.
  4. Endpoint Security: Endpoint security works to safeguard mobiles, desktops, laptops and tablets, etc. from cyber threats.
  5. Mobile Security: With mobile phones and tablets having access to all corporate data, it needs digital security from all phishing and other malicious attacks.
  6. IoT Security: It involves various protocols and techniques to safeguard the network and connected devices.
  7. Information Security: It secures the privacy of data, both in transit and at rest. It secures the information from unwanted access, misuse and disruption.
