Chapter 8 - Human Element Security

Introduction: Providing security against people (employees, contractors, partners, customers, service providers) is a major challenge in information security. Human behavior is unpredictable, and people can be vulnerable to both innocent mistakes and malicious attacks.
Humans: The Weak Link: Security professionals focus on technical and physical controls but human errors (bad decisions) can easily negate those controls.
Security Awareness: User awareness is crucial to ongoing security. Core items frequently addressed include protecting data, passwords, social engineering, network usage, malware, personal equipment, clean desks, and policy knowledge.
Protecting Data: Data security is bound by numerous regulations (PCI-DSS, HIPAA, FERPA) impacting business practices.
Compliance on Protecting Data: Maintaining data protection is necessary due to reputation management and customer retention concerns. Penalties (suspensions, fines, jail) can result from non-compliance. Regularly covering data security in training is vital.
Passwords: Password security measures should balance complexity with the importance of what they protect. Strong passwords often include at least eight characters, upper and lower case letters, symbols, and numbers.
Password Expiration: Password expiry policies (e.g., every 90 days) reduce password reuse risks. New passwords should not resemble previous ones.
Passwords Syncing: Users manually synchronizing passwords across multiple systems increase security vulnerability.
Passwords Misuse: Compromised password databases and exposure of login credentials are serious threats.
Social Engineering: This involves exploiting trust and social behaviour to achieve malicious goals. Common examples include pretexting, phishing, spear phishing, tailgating, and baiting.
Pretexting: Fraudsters impersonate trusted authorities. The victim reveals sensitive information in response to the staged scenario.
Pretexting Scenario: Successfully social engineering a security guard might not be possible, and depends on the competence of the guard and the social engineer. Providing details of the organization is essential when attempting pretexting.
Phishing: Exploiting email, texting, and calls to deceive users. Attackers send convincing emails, with links to fake sites and attempt to gather credentials and install malware.
Spear Phishing: Targeted phishing campaigns focus on specific individuals or organizations, using detailed reconnaissance, increasing the success rate. Victims often trust the sender and perceive the information as legitimate.
Tailgating: This is when an unauthorised person follows an authorised person through a restricted area.
Malware: Malware (malicious software) includes viruses, worms, Trojans, ransomware, and spyware.
Malware Sources: Malware often arrives from email attachments, shortened URLs, or non-official download sites. Pirated software is also a popular source.
