6 What We re Doing What am I telling you?
7 What I m telling you How to leverage security features you have and start down a holistic security path.
8 What We re Doing Why am I telling you this?
9 Why I m telling you You have goals. You have bosses. We want to help.
10 What We re Doing Why hasn t someone else told you this?
11 Why they haven t told you They want to sell you stuff. If you don t buy more stuff, their bosses get mad.
12 Why they haven t told you But, we don t care about their bosses.
13 What we ll be covering The Business of Security understanding goals and options Back to Bare Essentials working towards holistic security Tapping into Technologies ways to leverage what you have Getting Started ideas to get you going
15 The Business of Security
16 The quest for goals, smart use of resources and ways to keep your bosses boss happy.
17 Moving toward a goal Agency IT Department Your Team Your Projects Regulations Security Compliance Customer Serving Public Inter agency
18 Moving toward a goal Agency IT Department Your Team Your Projects
19 Focus on resources Bigger focus on Budget using resources wisely Assets Agency Staff Time
20 Focus on resources Adapt for the Budget resources available Assets Agency Staff Time
21 Focus on resources Balance what s Budget missing with what s abundant Assets Agency Staff Time
22 Current projects What are you working on now and in the next 12 months?
23 Ways to meet goals Options Buy some more stuff Use what you have Get someone else to do it
24 For your projects Which one are you planning to do? And why?
25 What we re buying There are plenty of manufacturers and vendors that would like your money.
26 NAC Endpoint Security Enhanced AV Guest Solutions Wireless Security Firewalls/IDS Data Leakage ID Management SIEM Encryption They want us to buy all this
27 Side effects of new stuff Training Budget Services Resources For staff and end users To buy new products For install, configure & support Manage and maintain
28 Side effects of new stuff What s the real TCO involved with new products?
29 Balancing the real TCO TCO + TCO
30 The question Is buying new stuff the solution?
31 The answer Probably NOT
32 For your projects Would you use what you have if that were an option?
34 Back to Bare Essentials
35 The quest for holistic network security and the realization of ignorance.
36 Using what you have Leveraging Leveraging built in features Retooling Retooling the infrastructure Designing Designing for security from the start
37 Leveraging what you have Use features and tools built in to the products you have.
38 Retooling the infrastructure Reengineer the network for security and availability.
39 Design for security early Architect security into solutions at the start.
40 Holistic security snippets Access Control 0 Day User Control Management Using switches instead of NAC Using sflow instead of IDS Using directories instead of overlays Using effective logging and reporting
41 A simple concept It seems so simple, so why aren t more people doing it?
42 Holistic holdbacks There are several common factors that prevent IT departments from effectively using what they have.
43 Holistic holdbacks Under staffing and high turnover are problems Staff Skill May not have necessary skills in house Redesign and training is time consuming Time
44 Holistic holdbacks Awareness of current environment Documentation Complexity Complicated vendor specific features Pulling pieces together for an integrated solution Integration
45 Holistic holdbacks Not knowing what products and solutions you have Ignorance Understanding The overall goals and objectives Getting buy in from management Management
47 Tap Into Technologies
48 The quest for finding added functionality in your current stuff so we don t have to buy new stuff.
49 Tapping what you have Switch Firewall Encryption Management Coming Soon
50 Here are slide references to the cool stuff you missed, including the new 802.1X REV overview
51 Switches and wireless VLANs (Virtual LANs) Switch Not new Protects by segregating network traffic Lets you logically segment and secure instead of physically separating
52 Switches and wireless 802.1X Port Security Switch Also not new Protects unauthorized users from connecting to a port or wireless SSID Uses standard communication to lock ports until the user is authenticated
53 Switches and wireless MAC Lockdown (Port Security) Switch Protects unauthorized devices from connecting Statically set or dynamically learns allowed MACs
54 Switches and wireless Switch Dynamic IP Lockdown (IP Source Guard) Protects from statically set IP addresses Tracks DHCP results to match IP to MAC port VLAN
55 Switches and wireless Switch Source Port Filtering (Protected Ports) Protects devices from communicating directly Similar to wireless communication segregation for endpoints
56 Switches and wireless DHCP Snooping Switch Protects from rogue DHCP servers Maps known servers with its MAC address to an assigned port
57 Switches and wireless Dynamic ARP Protection/Inspection Switch Protects from ARP cache poisoning ARP matches MAC to IP Sees spoofed MAC addresses and ARP flood attacks
58 Switches and wireless Dynamic Port Mirroring Switch Not direct security feature Lets you offload traffic for security inspection with low overhead
59 Switches and wireless Other monitors Monitor for port scanning by watching for packets sent to closed TCP/UDP ports Monitor for DoS attacks from IP flooding by watching for a volume of new learned Ips Monitor for viruses by watching for sudden increase in ARP requests Monitor for other DoS attacks by monitoring system resources
60 Switches and wireless Other monitors Monitor for management intrusion by watching for failed logins Monitor for other attacks by watching for excessive or unexpected events new or moving MAC addresses and IP addresses, system resources
61 Switches and wireless Switch VLANs 802.1X MAC Lockdown Dynamic IP Lockdown Source Port Filtering DHCP Snooping Dynamic ARP Protection Dynamic Port Mirroring Other Monitoring
62 Tapping what you have Switch Firewall Encryption Management Coming Soon
63 Firewall, UTM and IDS Firewall
64 Firewall, UTM and IDS Gateway Security and UTM Firewall Use built in anti virus and anti spyware for an added layer of protection without a separate appliance Use integrated IDS/IPS instead of purchasing an additional solution
65 Firewall, UTM and IDS Application Security Firewall Use a firewall to apply application access control up to layer 7 Add security by using encrypted VPN connections on the LAN to access sensitive data
66 Firewall, UTM and IDS Network Segregation Firewall Use firewall logical zones and routes for segregation of LAN traffic
67 Firewall, UTM and IDS Inspection Firewall Offload or mirror internal network traffic to your firewall or IDS for further inspection to supplement NBAD
68 We re really gettin crazy now!
69 Tapping what you have Switch Firewall Encryption Management Coming Soon
70 Encryption Encryption
71 Encryption Data Protection Encryption Use encryption to secure sensitive data on endpoints and storage
72 Encryption Key Management Encryption Used your encryption product for centralized key management Map to your user directory for added security and reduced management Use single product for FDE, removable media, mail and other applications
73 Tapping what you have Switch Firewall Encryption Management Coming Soon
74 Management Management
75 Management 0 Day Protection Management Use integrated tools for NBAD (network behavior anomaly detection) Collect sflow/netflow from switches and wireless to see real time problems
76 Management Inventory Management Use current management systems such as patching and anti virus servers for asset inventory Use inventory reports to identify unpatched and unhealthy devices
77 Management Event Correlation Management Use built in management, search tools or syslogs for event correlation Data can be used for compliance reporting and change management
78 Management Log Management & Reporting Management Use a central log server or search tool for all your network devices, instead of manufacturer specific products
