Common threats that IT managers may encounter include ransom ware, phishing attacks, and malware. IT security is akin to a digital lock, which deters these threats besides preventing unauthorized persons from accessing confidential information such as credit card numbers and bank accounts.

The objective of IT security is to enhance the availability, confidentiality, and integrity of computer systems. In doing so, sensitive data will only be made available to authorized individuals. A foolproof security system equally prevents the unauthorized alteration of data.

  • Updating Networks Regularly: After securing all network access points using strong passwords, IT managers need to make a deliberate effort to make their networks safe from other hazardous attacks. Typically, cybercriminals prefer attacking old versions of softwares due to the presence of loopholes. To avoid this, operating systems, device drivers, firmware and antivirus in all endpoint devices should be regularly updated.
