Study Notes
Security Concerns
- Unauthorized users accessing sensitive corporate data (e.g., disgruntled ex-employees, hackers).
- Intercepting/listening to network traffic (especially wireless).
- Malicious outside attacks on network servers.
- Property/data loss due to theft.
- Property/data loss due to fire.
- Online transactions.
- Viral infections.
User Security Solutions
- Firewalls (hardware or software).
- Strict user permissions limiting access to necessary data.
- Authentication methods.
- Data encryption to prevent interception.
- Regularly updated antivirus software.
- Local policies restricting system capabilities.
- Limiting system access (e.g., no removable drives).
Physical Security Solutions
- Theft prevention (e.g., tamper-resistant screws, alarms).
- Closed circuit monitoring.
- Regular hardware inventory.
- Secure system anchors and locks.
- Physical authentication (e.g., proximity cards, fingerprint readers).
- Limited server access.
Social Engineering
- Social engineering is a type of "hacking" that manipulates people to gain unauthorized access.
- Phishing.
- Impersonation.
- Shoulder surfing.
- Baiting (leaving a decoy to lure users).
- Identity theft.
Plan for Disaster
- Make daily server backups and mirrors (one on-site, one off-site).
- Maintain extra hardware for quick replacements to minimize downtime.
- Prepare a plan for various disasters (e.g., server crash, drive failure, network attack, theft).
- Begin damage control.
Disaster Prevention
- Disasters are inevitable.
- Maintain optimal server/equipment room conditions (temperature, location).
- Avoid basements to reduce flood damage.
- Use high-quality surge protection and backup power systems.
- Implementing deterrents to reduce theft.
Disaster Prevention (User Focus)
- Educate users about security risks.
- Implement backup/restore system images.
- Avoid concealing file extensions.
- Implement software undoing unauthorized changes.
Disaster Prevention (Technical)
- Use the correct tools (e.g., do not substitute network intrusion software for firewalls).
- Understand personal legal/financial liabilities relating to data breaches.
- If transporting off-site data, be mindful of potential consequences for data falling into the wrong hands.
More Points About Security
- Act as a security advocate to protect data and assets.
- Methods used to compromise security evolve, so constant vigilance is required.
A Few More Security Tips
- Security policies exist (all employees must be familiar).
- Rename administrator accounts and create false accounts (hackers often target Administrator accounts).
- Limit login attempts to protect accounts.
Backups
- Backup strategies typically involve a full backup at the beginning of the week.
- Subsequent backups can be differential (changes since last full) or incremental (changes since last backup).
- Backup frequency depends on department access patterns.
Authentication
- Authentication validates user identity accessing a resource.
- Two-factor authentication is common (something you are, have, or know).
- Periodic authentication is often required within a system.
Secure Deletion of Data
- Hard drives: software overwrites data repeatedly (e.g., DBAN), degaussing or physical destruction.
- Optical disks: many shredders have slots for disks; employing industrial shredding services is advised for discarded EOL devices.
Security (Policy & Procedures)
- Principle of Least Privilege: users only have access to the information necessary for their jobs.
- Chain of Custody: detailed documentation trails the handling of evidence.
Security (Methods)
- Mantrap: secure area allowing only one person at a time to pass (mitigates tailgating).
- Honeypot: decoy server to lure attackers and gather threat intelligence.
Passwords
- Encourage/force regular password changes.
- Longer, more complex passwords (upper/lowercase, numbers, symbols) are better.
- Avoid reusing passwords for multiple accounts.
Password Confidentiality
- Studies show significant percentages of workers share passwords for small incentives.
- Password security is crucial, and companies need to implement safeguards and policies to prevent breaches.
