  2. Chapter 4 Review Monitoring Activity and Intrusion Detection Monitoring the Network Understanding Intrusion Detection Systems (IDS) Working with Wireless Systems Understanding Instant Messaging Features Working with 8.3 File Naming Understanding Protocol Analyzers Understanding Signal Analysis and Intelligence Footprinting Scanning

  3. Chapter 4 REVIEW Quick check of concepts… • Quickly type your response to these questions: #1 What is NFS and why do we care? • #2 With IDS there is a data source. What makes up the raw information in the data source? • #3 Name a problem with Host-Based IDS. • #4 Bonus: Why should you discard WEP for WPA2?

  12. Chapter 5 Network Security Threats (continued) Listen to podcasts: http://www.govinfosecurity.com/interviews (See black bar under title, hit triangle) Interview with Chris Novak (May 11, 2012) 15 minutes http://www.govinfosecurity.com/interviews/improving-breach-investigations-i-1560Improving Breach Investigations - In short, organizations need to know where data is stored and what it comprises. But Novak says most organizations have too much data and in too many places to manage. Many organizations just struggle with understanding the picture of the data problem," says Novak, a member of Verizon's investigative response team. "They don't necessarily know where they have data ... and how it's being handled." Fraud Fighters Wanted (July 5, 2011) 13 minutes http://www.govinfosecurity.com/podcasts.php?podcastID=1177 Global Threats Create Boom Times for Fraud Examiners Today's top fraud threats recognize no global boundaries, says James Ratley, head of the Association of Certified Fraud Examiners.

  13. Chapter 5 Nessus and NMAP Nessus - vulnerability scanner that was a free and open source vulnerability scanner until they closed the source code in 2005 and removed the free "registered feed" version in 2008 http://www.nessus.org/products/nessus Nmap ("Network Mapper") is a free and open source utility for network exploration or security auditing. http://nmap.org/

  14. Chapter 5 Security Baselines • Back to the book…pg 222 • What is a security baseline? • “The base level of security that will be implemented and maintained.” • Depending on the environment, baseline security may include layers of protection, such as encryption, filtering, access control lists, authorization and authentication, and other security functions. • Tools to help: • Baseline: http://www.computerbaseline.com/ Demo explains this product. • VMWare/Shavlik – patch management, etc. • Qualys: policy management, vulnerability scanning, etc.

  15. Chapter 5 Security Baselines (continued) Microsoft tools for baselines: Microsoft Security TechCenter – Patch Tuesday, Windows Update http://technet.microsoft.com/en-us/security Microsoft Security Compliance Manager (SCM) http://technet.microsoft.com/en-us/solutionaccelerators/cc835245 http://social.technet.microsoft.com/wiki/contents/articles/774.microsoft-security-compliance-manager-scm-en-us.aspx “baselines are based on Microsoft Security guide recommendations and industry best practices, allowing you to manage configuration drift, address compliance requirements, and reduce security threats.Microsoft Baseline Security Analyzer http://technet.microsoft.com/en-us/security/cc184922#EWBAC Security Configuration Wizard (SCW) - attack-surface reduction tool included with Windows Server 2008 R2. SCW guides administrators in creating security policies based on the minimum functionality required for a server's role or roles.

  16. Chapter 5 Security Baselines • Common Criteria (CC) • Evaluation Assurance Levels (EALs) • EAL 1 • EAL 2 • EAL 3 • EAL 4 – Recommended for commercial systems –Windows 7 • EAL 5 • EAL 6 • EAL 7

  17. Chapter 5 Hardening the OS and NOS • Configuring Network Protocols • Hardening Microsoft Windows Vista/Windows 7 • Hardening Microsoft Windows XP • Hardening Windows Server 2003/Server 2008 • Hardening Windows Server 2000 • Hardening Unix/Linux • Hardening Novell NetWare • Hardening Apple Macintosh

  18. Chapter 5 Hardening the OS and NOS Windows Service Hardening restricts critical Windows services from running abnormal activities in the file system, registry, network or other areas that could be exploited by malware.  Ex: Install Windows Server 2008 as a Server Core installation. Server Core provides a minimal environment for running specific server roles, reducing maintenance and management requirements and the attack surface. Windows services represent a large percentage of the overall attack surface. Windows Server 2008 limits the number of services that are running and operational by default.  Security Configuration Wizard – examines roles, adjusts to role

  19. Chapter 5 Hardening the OS and NOS • Hardening Filesystems • NTFS, Unix NFS, Apple AFS • Updating Your Operating System • Hotfixes, Service Packs and Support Packs, Patches • Microsoft Patch Tuesday: Monthly Security Bulletins • http://technet.microsoft.com/en-us/security/bulletin/ms12-may • Articles - Help: I Got Hacked. Now What Do I Do? • http://technet.microsoft.com/en-us/library/cc700813.aspx • Jesper M. Johansson, Ph.D., CISSP, MCSE, MCP+ISecurity Program Manager, Microsoft Corporation • “After the very long Patch Management article last month, this month’s article is much shorter and to the point. Let’s just say you did not install the patches like we discussed last month. Now you got hacked. What to do?”

  20. Chapter 5 Hardening Network Devices • Updating Network Devices • Configuring Routers and Firewalls • Patches and Updates for Routers and Firewalls • Enabling/Disabling Services and Protocols • Working with Access Control Lists (ACLs)

  21. Chapter 5 Application Hardening Web Servers E-mail Servers FTP Servers DNS Servers NNTP Servers File and Print Servers and Services DHCP Services Data Repositories

  22. Chapter 5 Application Hardening (cont) • Web Servers – IIS, Apache, anonymous, executable scripts, uploads, etc. • DNS Servers • http://www.networksolutions.com/whois/index.jsp • http://www.whois.net • Data Repositories • Directory Services – LDAP, Active Directory, X.500, SQL

  23. Chapter 5 Unit 5 Assignment Unit 5 Project – Two Parts

  24. Chapter 5 Unit 5 Project Assignment TWO PARTS! Essay questions 30 points for Part 1 1.1. Pick one NOS and one OS and describe the process of hardening it from attacks and intruders. (i.e. Windows XP and Windows Server 2008 ORWindows 7 and Linux Ubuntu) 1.2. Pick two application server types listed in the text (pg. 240 to 246) and describe the process of hardening them from attacks and intruders 20 points for Part 2- at least four paragraphs Based on the knowledge you have achieved thus far in our class, compose a brief synopsis compiling what you have learned about network security. Describe how you will use this knowledge with any other class, your present or future career, or your own personal life. APA Style for both Part 1 and Part 2.
