5 Information Security OECD, April 2001 International Computing Centre Key components Ownership and culture Policies Processes and tools Autopsies, diagnostics, audits

6 Information Security OECD, April 2001 International Computing Centre Ownership Anybody Somebody Everybody Nobody

7 Information Security OECD, April 2001 International Computing Centre Culture Security management is a way of life It relies on everyone It requires many processes It may contain many projects but it has no end Only the paranoid survive

8 Information Security OECD, April 2001 International Computing Centre Threatscape Internal External Physical Logical Sabotage Misuse/ fraud Unauthorised access Unauthorised change Unauthorised disclosure Destruction of data Malicious software Stupidity Weaknesses in systems Weaknesses in products Cyber-attack (DoS/ DDoS) Cyber-attack (EMP) Data blackmail and many more...

9 Information Security OECD, April 2001 International Computing Centre Threatscape (2) Most pervasiveMost expensive Most publicisedMost frequent Virus, worm, trojan horse Insider fraud, sabotage Theft of proprietary information Attacks on e-business - theft of credit card data - Denial of Service Developers’ mistakes Poor configuration Poor system administration

10 Information Security OECD, April 2001 International Computing Centre Building blocks Change Control Backup /restore Media management Disaster recovery Business continuity Crisis management Physical access control Logical access control Infrastructure - No single point of failure - UPS and standby - Clusters, fail-soft, alternative routing, RAID, … Diagnostics and monitoring System administration Audits Policies Best practices Standards Action plans Key word: OWNERSHIP

11 Information Security OECD, April 2001 International Computing Centre Building blocks (2) Confidentiality Integrity Authorisation Authentication Audit trail Non-repudiation Risk assessment Communications Risk management Alert monitoring Tools and products Organisation - incident detection - incident response Staff vetting Training Tests and audits Key word: OWNERSHIP

12 Information Security OECD, April 2001 International Computing Centre Policies Scope Documentation Dissemination Maintenance Compliance Non-compliance

14 Information Security OECD, April 2001 International Computing Centre Scope of policies (2) 9 Acceptable use 9 Monitoring and audits 9 Mobile computing 9 Wireless computing 9 Privacy 9 Staff background checks and more...

15 Information Security OECD, April 2001 International Computing Centre e-mail policy includes... < Virus, worm, other infectious software < Executable code < Audio and video files < Other large files < Encryption < Non-disclosure < Offensive language/material < Legal liability (harassment, copyright, libel, etc) < Junk e-mail and other loss of productivity < Personal use of corporate e-mail < Archival and so on...

16 Information Security OECD, April 2001 International Computing Centre Vigilance Alerts (Vendor, CERT, FBI, other) Attacks (who, when, how) Hacker tools, communiques, websites Disgruntled staff, behavioural changes etc

17 Information Security OECD, April 2001 International Computing Centre Security rings Data access rights Database security System security LAN and server security Firewall security Authentication etc What does it take to get through each of these layers

18 Information Security OECD, April 2001 International Computing Centre Tools and products Firewalls and antivirus software Resource access controls Encryption Digital certificates Proxy / Reverse Proxy servers Intrusion detection systems Software integrity checkers Log analysis tools and so on... “out of the box” may not be e-nough many choices

19 Information Security OECD, April 2001 International Computing Centre Certification, audits, etc d tests d audits d post-mortems d certification Like your annual medical it’s no guarantee of good health but it might diagnose a problem Who tests the testers? How do you know you have not been attacked ?

20 Information Security OECD, April 2001 International Computing Centre Be vigilant, be silent...
