Summary – Securing Information Systems


Amidst the rise of a more connected business, entities also needs to be aware of any threat coming in form of cybersecurity issue. Digital data are really vulnerable to destruction, misuse, error, fraud, and hardware or software failures. The Internet is designed to be an open system and makes internal corporate systems more vulnerable to actions from outsiders.

Furthermore, lack of sound security and control can cause firms relying on computer systems for their core business functions to lose sales and productivity. Information assets, such as confidential employee records, trade secrets, or business plans, lose much of their value if they are revealed to outsiders or if they expose the firm to legal liability. Several well-known case in the past includes Yahoo and Marriott.

To prevent any wrongdoings happened from this issue, firms need to establish a good set of both general and application controls for their information systems. A risk assessment, corporate security policy, and comprehensive and systematic information systems auditing is several ways that entities could do.

Tools and technologies that are essentially needed for safeguarding information resources includes firewall; intrusion detection system; passwords, tokens, smart cards and biometric authentication; antivirus software; antispyware; encryption, coding, and scrambling of message; digital certificates combined with public key encryption; fault-tolerant computer systems; and use of software metrics and rigorous software testing.
