In many cases, a network device s primary protection method is a password Good passwords are one of the most effective security tools, because a good password can be resistant to several forms of attack This resistance makes an attacker use simple bruteforcing methods, taking tremendous amounts of time and generating a large amount of network traffic, both increasing the likelihood of the attacker s efforts being detected Unfortunately, good passwords are often hard to remember, so weaker passwords are usually used To recognize the impact on security that a bad password can have, consider the fact that a typical brute-force program can try every word in the unabridged English dictionary in less than a day, but it would take several thousand years to attempt to brute-force an eight-character password This is based upon using not only the standard 26-character alphabet, but also adding capitalization for 26 more characters, numeric digits for 10 more, and special characters, adding another 32 different characters This totals 95 different characters that can be used, giving 6,704,780,954,517,120, or 6 quadrillion different possibilities for a one- to eight-character password This is in stark contrast to the estimated 2 million words in the English language, or the 217 billion possibilities provided by simple lowercase alphabetic characters The best kinds of passwords bear no resemblance to actual words, such as AvhB42^&nFh However, although such passwords provide greater security, they are difficult to remember, leading users to choose passwords that are based on regular dictionary words While this is a concern for any password on any system, it is of greater concern on network infrastructure equipment, because many pieces of network equipment require only password authentication for access typically, no username is required One of the password-related issues that many administrators overlook is SNMP, which was developed in 1988 and has been implemented on a huge variety of network devices Its wide implementation is directly related to its simplicity and extensibility Since every manufacturer can add objects to the Management Information Base (MIB), one manufacturer can add functionality without interfering with any other manufacturer s portion of the MIB tree This feature of the protocol lets manufacturers make SNMP very powerful for configuration and monitoring purposes The downside is that many devices have SNMP turned on by default Network administrators not using SNMP will often forget to disable SNMP or will forget to change the well-known default passwords typically public for read-only access and private for read/write access With the SNMP service active and using a default password, an attacker can retrieve a great deal of interesting information from a network device, as well as altering any SNMP-capable settings If SNMP is employed, well-thought-out passwords should be used, as well as a schedule for password updates EXAM TIP The use of the word public as a public SNMP community string is an extremely well-known vulnerability Any system using an SNMP community string of public should be changed immediately Keep in mind that SNMP passwords are often passed in the clear, so it should never be treated as a trusted protocol The SNMP service should also be limited only to.

Cochannel Interference Interference caused by two or more television broadcast stations utilizing the same transmission channel in different cities It is a form of interference that affects only broadcast television

near/far A term used to describe the problem that arises when wireless nodes are far from the access point transmitting with low power and other wireless nodes are closer to the access point or transmitting with higher power This results in the far node not being seen by the access point and, therefore, having difficulty communicating omnidirectional antennas Antennas that radio energy in a donut fashion around the antenna These include dipole and rubber-ducky antenna types open system authentication The default authentication for the IEEE 80211 specification Shared-key authentication is the alternative The authenticating station sends a frame to the other station (an access point in infrastructure mode) requesting authentication and containing the authenticating station s identification The receiving station (again, the access point in an infrastructure network) sends back a frame that either authenticates access or denies access to the authenticating station Open system authentication is used with 8021X port-based authentication solutions suggested in 80211i PCI Peripheral Component Interconnect (PCI) is a high-speed connection port for devices attached to computers Some wireless network interface cards (NICs) use PCI slots for their interface connections PCMCIA Personal Computer Memory Card International Association (PCMCIA) is an interface used to connect devices to laptop computers Some wireless network interface cards (NICs) use PCMCIA interfaces PCMCIA cards often function in the newer CardBus slots on modern laptop computers Today, PCMCIA devices are often called PC Card devices point-to-multipoint A wireless link that includes multiple points connecting to a single central point This is much like a star network topology in that all the sites communicate back to the central location point-to-point other system

connections from the management station s IP address If SNMP is not used, the service should be disabled, if possible Otherwise, the ports for SNMP should not be accessible from anywhere on the external or internal network As with any system, security is largely dependent on proper configuration of the system itself A router can be secured with proper configuration just as easily as it can be left unsecured through poor configuration Good passwords and knowledge of what services the devices are running is important to maintaining the security of those devices
