As a research tool, Google was a great help to a law school student as she gathered online research sources for her thesis on money laundering. As you can imagine, this was definitely a great tool to her in the process of writing her thesis. Soon, she began to have the problem of her search terms taking her to pages completely unrelated to money laundering.

After the persistency of the problem caused the student to rethink her initial belief of a problem within the search engine or her internet system, she quickly came to realize someone had bugged her. Whenever we are bothered by human annoyances, those are easily dealt with. Stopping adware and spyware, the type of bugs that plagued the student, is much more difficult. The law school student was definitely not an advanced student of technology, as she typically only used her computer for school related purposes of research and writing.

Seemingly complex computer problems that boggle the minds of most computer uses, like the law student, can typically be summed up with the words spyware and adware. Though it did not gain popularity until 2000, the term ’spyware’ was first introduced in 1995. This refers to any software program or script which allows admission to the computer owner’s personal information.

This can be done through studying keystrokes, logging web browsing activities, and perhaps most worrying of all, the contents stored on a user’s hard drive. The scary spy tactics used by spies in Hollywood movies are nothing next to the very real and present danger afforded by spyware to everyone who owns a computer. The invasive monitoring of internet activities makes it safe to call those affected victims. Spying on criminals with spyware makes sense because it can help society for the greater good, but too often this program is used to track sensitive personal information, such as credit card information. The need for a great, up to date anti-spyware program should be obvious.

While blocking spyware, you should also block adware and malware to fully protect your system. Online adware and spyware blocker programs are easily available to help in this endeavor. Spyware, adware, and malware prove that computer bugs do not have to be self replicating, like viruses and worms, to prevent the normal usage of computers. Unfortunately, the immense slowing down of infected computers is one of the side effects that can result from these programs. Despite sluggish systems and continual privacy invasions, some spyware programs are able to hide themselves well enough to prevent anyone from identifying them as the culprit. The best way to prevent the side effects of these malevolent programs is to install a good blocker to stop them from downloading onto your system.

Get your CCNA and CCNP certifications with The Bryant Advantage!

When you started studying for your CCNA certification exam, one of the very first things you learned was the major difference between the enable password and the enable secret - the enable secret is encrypted by default, where the enable password is just sitting there in clear text, waiting to be read!

When you look at the enable secret in a Cisco router configuration, it looks like it would be impossible to guess. After setting the enable secret on this router to the word security, here’s how it appears in the configuration:

enable secret 5 $1$24me$gVFxUOI4gYp0IQbhtH8Rz0

That password has been encrypted by MD5, the Message Digest 5 algorithm. The result of the MD5 algorithm being applied to the password is a 32-character hexadecimal value.

That password is hard to guess, but not terribly hard to crack. Anyone looking over your shoulder would not be able to come up with that password, but there are readily-available password cracking software devices that can crack that encryption in a matter of minutes. That’s true of any MD5-encrypted password, not just those on Cisco routers.

So what can we do about this? We can add SALT to our MD5.

The salt itself is simply a string of random characters that are added to the encryption process. Salting makes it much more difficult for a hacker to come up with the password; each bit added by the salt process literally makes it twice as difficult for the password to be compromised. A recent Wikipedia entry states that if a password was one of 200,000 words, a 32-bit salt would require 800 trillion hashes for a full-blown brute force attack.

The actual creation and application of a salt is beyond the scope of the CCNA Security exam, but once you’ve earned that valuable certification - or maybe while you’re preparing for it - do a Google search on “salt md5″ and read up on this powerful security tool. In the meantime, look for more CCNA Security tutorials on the site you’re on now as well as my website!

Whether we’re routing or switching, we’re always glad to have all the redundancy we can get! With switches, we’re particularly happy to have multiple paths between two given points. Redundancy does present a potential problem with switches, however.

Here are some short answer Cisco certification exam practice questions to help you prepare for success on exam day! Answers are at the end of the article. No peeking!

CCNA Certification And CCENT Certification:

Three questions for you:

What potential issue does this topology pose?

What protocol can help avoid that issue?

Assuming the switches are running at their defaults, what do we need to do to enable that protocol?

.

CCNA Security Certification / CCNP ISCW Exam:

What is the net effect of the following configuration?

R1(config)#access-list 110 permit tcp any 10.0.0.0 0.255.255.255

R1(config)#ip tcp intercept list 110

CCNP Certification / BSCI Exam:

What’s the main difference between the following two BGP community values?

NO-EXPORT

NO-ADVERTISE
.

CCNP Certification / BCMSN Exam:

What command will assign a MAC address of 11-22-33-44-55-66 to the virtual router in HSRP group 5?

CCNP / ONT Exam:

What’s the basic purpose of Voice Activity Detection?

Here are the answers!

CCNA / CCENT Answers: If these redundant paths are all open at the same time, we have the potential for switching loops to form. The Spanning-Tree Protocol (STP) helps to prevent these loops. If these Cisco switches are at their default, we don’t need to do anything to enable STP - it’s enabled by default.

CCNA Security / ISCW Answer: To configure an ACL to define the source and destination of packets that should be subject to TCP Intercept, write the ACL and then apply it with the ip tcp intercept list command. Most likely, you’ll specify a source of “any”, as I did in the above example.

BSCI Answer:

NO-EXPORT: Marking a route with this community attribute prevents it from being advertised to an eBGP peer.

NO-ADVERTISE: Taking the previous community one step further, this community attribute prevents the route from being advertised to ANY other router.

BCMSN Answer: On rare occasions, you may have to change the MAC address assigned to the virtual router. This is done with the standby mac-address command. Just make sure you’re not duplicating a MAC address that’s already on your network!

ONT Answer: VAD detects voice activity, and perhaps more importantly, it detects when there is no voice activity. When there is no talking on a call using VAD, no audio packets are transmitted. Studies show that a normal conversation is 35 - 40% silence, VAD can give us big-time bandwidth savings as well as cutting down on overall traffic.

Let’s test your knowledge of VTPs, BGP attributes, and other important Cisco certification exam topics!

CCNA Certification And CCENT Certification:

Identify the benefits of VTP.

A. Decreases amount of unnecessary broadcasts forwarded across a trunk

B. Dynamically bundles multiple trunks into one larger, logical trunk

C. Gives participating switches a like view of the network

D. Allows all switches to create and delete VLANs, regardless of mode

E. Allows admin to restrict which switches can and cannot delete VLANs

CCNP Certification / BSCI Exam:

What BGP attribute matches the following description?

“When BGP paths are aggregated (summarized), this well-known attribute indicates the router that performed the aggregation. This attribute gives notice to downstream routers that more-specific BGP routing information was lost at the point of aggregation.”

CCNP Certification / BCMSN Exam:

What are the basic steps to totally erase the configuration of a Cisco 2950 switch?

CCNP / ONT Exam:

What is “Survivable Remote Site Telephony”? What exactly are we surviving, and how?

.

Here are the answers!

CCNA / CCENT: Answers: A, C, E. Answer “A” describes VTP trunking, which is not enabled by default but is a benefit of VTP.

“B” describes an Etherchannel. Answer “D” is incorrect since VTP Clients cannot create and delete VLANs.

BSCI: Answer: Well, you knew it had something to do with aggregation, right? That paragraph describes the atomic aggregate attribute.

BCMSN: Answer: Outside of running write erase, you also want to run delete vlan.dat to totally initialize the switch. If you just erase the switch config and then reload, the switch will retain its VLAN information since that is kept in the vlan.dat file.

ONT: Answer: SRST allows a Cisco router to take the place of an unavailable CallManager cluster. While the WAN is down, the connection to the Public Switched Telephone Network (PSTN) remains, and this allows the IP Phones at that remote site to function in the absence of the CallManager cluster.
