Why Security??
 If the security is compromised, serious consequences,
such as loss of privacy, theft of information, legal
liability… result
 Types of potential threats to security are always
evolving
 E-business and Internet applications continue to growcannot avoid open networks
 Security has moved to the forefront of network
management and implementation – and this is
evident in the Academy Curricula

Security in IT E I
 Mainly in chapters 9 & 16
IT Essentials
 Major issues:
Security Threats – physical, data, internal vs external
Security procedures/techniques
Preventive maintenance techniques
Troubleshooting security

Security in IT E – Security procedures
WEP, WPA, WPA2(802.11i),
LEAP, mac filtering, ssid
broadcast, WTLS
Password protection,data
encryption, port
protection,backup, file system
security
Access control, cable
locks,security cages,RFID
tags,lock rooms
Identify: assets, threats
Define:-incident
handling,emergency ,allowed &
prohibited behaviour,security
framework, security techniques, ..

Preventive maintenance on security
 OS updates – automatic, notify, only download , off(no
updates)
 Antivirus & Antispyware – update signature files
 Account maintenance
Terminate employee access
Guest access
Group by job functions
 Data backup & access
Africa Academy Safari 2009
6
Security components & techniques
 The following techniques & components are discussed:
oPasswords - it is a minimum requirement
oLogging & auditing
oEncryption - encoding data for purposes such as
oHashing
oSymetric encryption
oAsymetric
oVirtual private networks
oFirewalls – hardware & software and could be
oPacket filter
oProxy firewall
oStateful packet inspection
oIDS
 Security expense vs cost of loss help establish tradeoffs

Proving security
 Security measures taken in a network
should:
• Prevent unauthorized disclosure or theft of
information
• Prevent unauthorized modification of
information
• Prevent Denial of Service
 Means to achieve these goals include:
• Ensuring confidentiality
• Maintaining communication integrity
• Ensuring availability
Africa Academy Safari 2009
11
Primary classes of attacks
Reconnaisance attacks –
internet information queries, ping
sweeps, port scans, packet
sniffers
Access Attacks -– password,
trust exploitation,port redirection,
man in the middle attack
DOS – Ping of D, Syn flood,
DDoS, …
Malicious Software – Virus,
Worm, Trojan horse – worms
require containment, inoculation ,
quarantining & treatment
Africa Academy Safari 2009
12
Securing Cisco Routers
 routers provide gateways to other networks, they are
obvious targets, and are subject to a variety of
attacks.
Africa Academy Safari 2009
13
Secure Routing protocols
 Major attacks: disrupt peer , falsify information
 Can configure passive int., authentication
R1(config)# router rip
R1(config)# passive-interface default
R1(config)#no passive-interface se0/0/0
R1(config)# key chain RIP_KEY
R1(config-keychain)#key 1
R1(config-keychain-key)# key-string cisco
R1(config)#int se0/0/0
R1(config-if)#ip rip authentication mode md5
R1(config-if)#ip rip authentication key-chain RIP_KEY
Africa Academy Safari 2009
Also EIGRP &
OSPF
authentication
14
Security Device Manager – SDM
 An easy-to-use, web-based device-management tool designed for
configuring LAN, WAN, and security features on Cisco IOS
software-based routers.
 Firewall, VPN, IPS/IDS,NAT, router lockdown
Africa Academy Safari 2009
15
VPNs
 VPNs - enable transportation of information in a private network
over a public network – encapsulation(tunneling) & encryption
typically used
Africa Academy Safari 2009
16
NAT/PAT
 Adds a degree of
privacy and security hides internal IP
addresses from
outside networks.
ip nat inside source ..
ip nat inside
ip nat outside

17
Wireless Security protocols
 In 802.11i - WPA uses TKIP and WPA2 employs AES
Africa Academy Safari 2009
18

Major points about Security & current
curricula
 It is evident that a lot of security concepts
are covered
 Most of the treatment is introductory
 In Network Security I & II(unsupported) there is great depth &
breath of coverage
 CCNP (ISCW) – less breath than NS 1 & 2 but still depth on
specific issues
 There is need for curricula to build on what
IT Essentials and CCNA gives

CCNA Security Overview
 A new course that provides students with in-depth network security
education and develop a comprehensive understanding of network
security concepts
 Provides students with knowledge and skills to design and support
Network Security
 Provides an experience-oriented course to prepare for entry-level
specialist jobs in network security
 Prepares students for CCNA Security certification (IINS 640-553
exam).
 CCNA Security course IS NOT a replacement for the current
Network Security 1 and Network Security 2 (NS1 and NS2)
