Q & A

Why are Information Systems vulnerable to destruction, error, and abuse?

Information systems are vulnerable due to several reasons: technology failure, human error, and the attraction of sensitive data to cybercriminals. Technology can fail or be attacked, humans can make mistakes or fall victim to social engineering, and sensitive data often makes businesses a target for hackers.

What is malware, and what are the different types mentioned in the script?

Malware is malicious software designed to harm computer systems or networks. The different types mentioned include viruses, worms, Trojan horses, SQL injection attacks, ransomware, spyware, adware, and root kits. Each type has distinct methods of attack and impact on systems.

How do viruses and worms differ from each other?

Viruses require a host program to spread, whereas worms can replicate themselves and spread across networks or the internet without needing a host. Both cause damage to systems, but worms can affect multiple systems simultaneously.

What is ransomware, and how does it impact businesses?

Ransomware is malware that encrypts files on a system, rendering them inaccessible. The attackers demand payment in exchange for the decryption key. It can cause significant disruption to businesses, particularly when critical data is held hostage.

What is the business value of security and control?

The business value of security and control is immense. Effective security measures protect sensitive data, ensure legal compliance, maintain trust with customers and partners, reduce the risk of downtime, and prevent disruptions that could impact business operations.

What is the role of policies and procedures in an organizational framework for security?

Policies and procedures provide a clear framework for security, setting rules and expectations for employees and stakeholders. They help ensure that security measures are consistently followed and that resources are protected.

What are access controls, and why are they important?

Access controls ensure that only authorized users can access sensitive data and systems. They are crucial for protecting business resources from unauthorized access and ensuring that data remains confidential.

What is the importance of physical security in protecting information systems?

Physical security is essential to protect the physical assets of a business, such as servers and data centers, from theft, damage, or unauthorized access. It complements cybersecurity measures by providing a holistic security approach.

What tools and technologies can be used to safeguard information resources?

Tools and technologies include firewalls to prevent unauthorized network access, encryption to protect sensitive data, antivirus software to detect malware, intrusion detection systems to monitor for threats, and virtual private networks (VPNs) to secure online data transmission.

What lessons can be learned from the 2016 cyber attack on the Swift global banking network?

The 2016 attack on the Swift banking network highlighted the vulnerability of global financial systems to cyberattacks. It emphasized the need for strong cybersecurity measures, including better authentication and monitoring systems, to protect financial transactions and systems from sophisticated attackers.
