10 Essentials of Security Dia 1

11 Business Case Security Risk Management Discipline Defense in Depth Security Incident Response Best Practices 10 Immutable Laws of Security

12 Impact of Security Breaches Loss of Revenue Damage to Reputation Loss or Compromise of Data Damage to Investor Confidence Legal Consequences Interruption of Business Processes Damage to Customer Confidence

13 2003 CSI/FBI Survey The cost of implementing security measures is not trivial; however, it is a fraction of the cost of mitigating security compromises

14 Benefits of Investing in Security Reduced downtime and costs associated with non-availability of systems and applications Reduced labor costs associated with inefficient security update deployment Reduced data loss due to viruses or information security breaches Increased protection of intellectual property

15 Security Risk Management Discipline Business Case Security Risk Management Discipline Defense in Depth Security Incident Response Best Practices 10 Immutable Laws of Security

16 Security Risk Management Discipline (SRMD) Processes Assessment  Assess and valuate assets  Identify security risks and threats  Analyze and prioritize security risks  Security risk tracking, planning, and scheduling Development and Implementation  Develop security remediation  Test security remediation  Capture security knowledge Operation  Reassess assets and security risks  Stabilize and deploy new or changed countermeasures

17 Assessment: Assess and Valuate Assets Asset Priorities (Scale of 1 to 10) – Example * * For example purposes only – not prescriptive guidance

18 Types of threats Examples S poofing Forge messages Replay authentication packets T ampering Alter data during transmission Change data in files R epudiation Delete a critical file and deny it Purchase a product and later deny it I nformation disclosure Expose information in error messages Expose code on Web sites D enial of service Flood a network with SYN packets Flood a network with forged ICMP packets E levation of privilege Exploit buffer overruns to gain system privileges Obtain administrator privileges illegitimately Assessment: Identify Security Risks and Threats – STRIDE

19 Assessment: Analyze and Prioritize Security Risks – DREAD DREAD  D amage  R eproducibility  E xploitability  A ffected Users  D iscoverability Risk Exposure = Asset Priority x Threat Rank Example Worksheet

20 Assessment: Security Risk Tracking, Planning, and Scheduling Types of threats Examples Spoofing Forge messages Replay authentication packets Tampering Alter data during transmission Change data in files Repudiation Delete a critical file and deny it Purchase a product and later deny it Information disclosure Expose information in error messages Expose code on Web sites Denial of service Flood a network with SYN packets Flood a network with forged ICMP packets Elevation of privilege Exploit buffer overruns to gain system privileges Obtain administrator privileges illegitimately Detailed Security Action Plans Example Worksheets

24 Defense in Depth Business Case Security Risk Management Discipline Defense in Depth Security Incident Response Best Practices 10 Immutable Laws of Security

25 The Defense-in-Depth Model Using a layered approach:  Increases an attacker’s risk of detection  Reduces an attacker’s chance of success OS hardening, authentication, patch management, HIDS Firewalls, Network Access Quarantine Control Guards, locks, tracking devices Network segments, IPSec, NIDS Application hardening, antivirus ACLs, encryption, EFS Security documents, user education Policies, Procedures, & Awareness Physical Security Perimeter Internal Network Host Application Data

26 Description of the Policies, Procedures, and Awareness Layer I think I will use my first name as a password. Hey, I need to configure a firewall. Which ports should I block? I think I will wedge the computer room door open. Much easier. They have blocked my favorite Web site. Lucky I have a modem.

27 Policies, Procedures, and Awareness Layer Compromise Say, I run a network too. How do you configure your firewalls? I can never think of a good password. What do you use? Hi, do you know where the computer room is? Hey, nice modem. What's the number of that line?

28 Policies, Procedures, and Awareness Layer Protection Firewall Configuration Procedure Physical Access Security Policy User Information Secrecy Policy Device Request Procedure Employee security training helps users support the security policy

29 Description of the Physical Security Layer All of the assets within an organization’s IT infrastructure must be physically secured

30 Physical Security Layer Compromise Install Malicious Code Damage Hardware View, Change, or Remove Files Remove Hardware

31 Physical Security Layer Protection Lock doors and install alarms Employ security personnel Enforce access procedures Monitor access Limit data input devices Use remote access tools to enhance security

32 Description of the Perimeter Layer Business Partner Internet Services LAN Main Office LAN Internet Services Branch Office Wireless Network LAN Network perimeters can include connections to: The Internet Branch offices Business partners Remote users Wireless networks Internet applications The Internet Branch offices Business partners Remote users Wireless networks Internet applications Remote User Internet

33 Perimeter Layer Compromise Business Partner Internet Services LAN Main Office LAN Internet Services Remote User Internet Branch Office Wireless Network LAN Network perimeter compromise may result in a successful: Attack on corporate network Attack on remote users Attack from business partners Attack from a branch office Attack on Internet services Attack from the Internet Attack on corporate network Attack on remote users Attack from business partners Attack from a branch office Attack on Internet services Attack from the Internet

34 Perimeter Layer Protection Business Partner Internet Services LAN Main Office LAN Internet Services Branch Office Wireless Network LAN Remote User Internet Network perimeter protection includes: Firewalls Blocking communication ports Port and IP address translation Virtual private networks (VPNs) Tunneling protocols VPN quarantine Firewalls Blocking communication ports Port and IP address translation Virtual private networks (VPNs) Tunneling protocols VPN quarantine

35 Description of the Internal Network Layer Sales Wireless Network Marketing Finance Human Resources

36 Internal Network Layer Compromise Unauthorized Access to Systems Access All Network Traffic Unauthorized Access to Wireless Networks Unexpected Communication Ports Sniff Packets from the Network

37 Internal Network Layer Protection Require mutual authentication Segment the network Encrypt network communications Restrict traffic even when it is segmented Sign network packets Implement IPSec port filters to restrict traffic to servers

38 Demonstration 1: Configuring IPSec Port Filtering Your instructor will demonstrate how to:  Create and configure an IP Security policy that contains IPSec port filters that will be used to lock down unnecessary ports on an IIS server  View IPSec port filter properties

39 Description of the Host Layer Contains individual computer systems on the network Often have specific roles or functions The term “host” is used to refer to both clients and servers

40 Host Layer Compromise Exploit Unsecured Operating System Configuration Exploit Operating System Weakness Unmonitored Access Distribute Viruses

41 Host Layer Protection Harden client and server operating systems Disable unnecessary services Keep security patches and service packs up to date Monitor and audit access and attempted access Install and maintain antivirus software Use firewalls

42 Windows XP SP2 Advanced Security Technologies Network protection Memory protection Safer handling More secure browsing Improved computer maintenance Get more information on Windows XP Service Pack 2 at Network protection Memory protection Safer handling More secure browsing Improved computer maintenance Get more information on Windows XP Service Pack 2 at
