What are Intrusion Detection Systems?

August 12, 2014 by  
Filed under General

Intrusion Detection System (IDS) are a necessary part of any strategy for enterprise security. What are Intrusion Detection systems? CERIAS, The Center for Education and Research in Information Assurance and Security, defines it this way:

“The purpose of an intrusion detection system (or IDS) is to detect unauthorized access or misuse of a computer system. Intrusion detection systems are kind of like burglar alarms for computers. They sound alarms and sometimes even take corrective action when an intruder or abuser is detected. Many different intrusion detection systems have been developed but the detection schemes generally fall into one of two categories, anomaly detection or misuse detection. Anomaly detectors look for behavior that deviates from normal system use. Misuse detectors look for behavior that matches a known attack scenario. A great deal of time and effort has been invested in intrusion detection, and this list provides links to many sites that discuss some of these efforts”(http://www.cerias.purdue.edu/about/history/coast_resources/intrusion_detection/)

There is a sub-category of intrusion detection systems called network intrusion detection systems (NIDS). These systems monitors packets on the network wire and looks for suspicious activity. Network intrusion detection systems can monitor many computers at a time over a network, while other intrusion detection systems may monitor only one.

Who is breaking into your system?

One common misconception of software hackers is that it is usually people outside your network who break into your systems and cause mayhem. The reality, especially for corporate workers, is that insiders can and usually do cause the majority of security breaches. Insiders often impersonate people with more privileges then themselves to gain access to sensitive information.

How do intruders break into your system?

The simplest and easiest way to break in is to let someone have physical access to a system. Despite the best of efforts, it is often impossible to stop someone once they have physical access to a machine. Also, if someone has an account on a system already, at a low permission level, another way to break in is to use tricks of the trade to be granted higher-level privileges through holes in your system. Finally, there are many ways to gain access to systems even if one is working remotely. Remote intrusion techniques have become harder and more complex to fight.

How does one stop intrusions?

There are several Freeware/shareware Intrusion Detection Systems as well as commercial intrusion detection systems.

Open Source Intrusion Detection Systems

Below are a few of the open source intrusion detection systems:

AIDE (http://sourceforge.net/projects/aide) Self-described as “AIDE (Advanced Intrusion Detection Environment) is a free replacement for Tripwire. It does the same things as the semi-free Tripwire and more. There are other free replacements available so why build a new one? All the other replacements do not achieve the level of Tripwire. And I wanted a program that would exceed the limitations of Tripwire.”

File System Saint (http://sourceforge.net/projects/fss) – Self-described as, “File System Saint is a lightweight host-based intrusion detection system with primary focus on speed and ease of use.”

Snort (www.snort.org) Self-described as “Snort® is an open source network intrusion prevention and detection system utilizing a rule-driven language, which combines the benefits of signature, protocol and anomaly based inspection methods. With millions of downloads to date, Snort is the most widely deployed intrusion detection and prevention technology worldwide and has become the de facto standard for the industry.”

Website Security Rules of the Road

August 12, 2014 by

In 2004, online consumer spending was at a record $65.1 billion. More and more people are attracted to the ease of online shopping and are spending higher amounts. Unfortunately, the chances of becoming a victim of Internet fraud are also increasing. The Internet National Fraud Center Watch reported that the average loss to fraud victims for just the first six months of 2005 was $2,579. This is compared to the $895 average for all of 2004. Complaints relating to general merchandise purchases (goods never received or misrepresented) accounted for 30% of Internet fraud complaints, and auction purchases (goods never received or misrepresented) topped the list at 44%.

While many e-commerce Websites are reputable and have taken the necessary safety precautions to protect you, it never hurts to always proceed cautiously. If you are making an online purchase consider these easy steps:

1 Use only one credit card, preferably with a low credit limit, when making online purchases. Avoid using an ATM or debit card.
2 Be wary of unsolicited offers by sellers. The Internet National Fraud Information Center Watch reported that email, as a method of contact by Internet scammers was up 22% in 2004.While the offer may be legitimate, spammers like to use this tactic to side-step reputable sites that provide consumer protection for online purchases.
3 Use only reputable e-commerce websites that list a street address and telephone number in case you need to contact them directly.
4 Read the website’s privacy policy. Some websites may reserve the right to sell/give your information to a third party. Check the document to see if they allow an opportunity to “opt-out” of receiving special offers from third-party vendors or for permission to share your personal information.
5 Check for a lock symbol in the status bar at the bottom of your Web browser window. Also, do not provide your personal information if the website address doesn’t start with “https” (a sign that the site is using a secure server).
6 Choose only verified sellers. Check to see if the vendor is a verified member of a reputable third party such as the Better Business Bureau, VeriSign, or Guardian eCommerce. These third-party sites help to ensure online consumers will be protected when shopping or conducting e-commerce transactions.
7 Check that the delivery date posted is reasonable. If you have not dealt with the vendor on a regular basis, be wary of any Website that states the shipment will be delayed 20 or more days. Delivery dates of 7-10 days are more common.
8 Keep a paper trail of all online transactions. Print out a hard copy of the transaction and keep it in a file for future reference.
9 Be wary of website offers that just sound too good to be true. The Internet is littered with get rich quick scams and false advertising claims. Investigate all claims thoroughly before proceeding.
10 If you do not receive what you paid for, and the vendor will not return your emails or calls, contact your state’s Department of Consumer Affairs for further assistance.

Trojan Horse….Greek Myth or Computer Nemesis?

August 12, 2014 by  
Filed under General

We have all heard the term Trojan Horse, but what exactly is it? A Trojan Horse is a destructive program that masquerades as a harmless application. Unlike viruses, Trojan Horses do not replicate themselves, but they can be just as destructive. One of the most dangerous examples of a Trojan is a program that promises to rid your computer of viruses but instead introduces viruses into your computer.

The Trojan can be tricky. Who hasn’t been online and had an advertisement pop up claiming to be able to rid your computer of some nasty virus? Or, even more frightening, you receive an email that claims to be alerting you to a new virus that can threaten your computer. The sender promises to quickly eradicate, or protect, your computer from viruses if you simply download their “free”, attached software into your computer. You may be skeptical but the software looks legitimate and the company sounds reputable. You proceed to take them up on their offer and download the software. In doing so, you have just potentially exposed yourself to a massive headache and your computer to a laundry list of ailments.

When a Trojan is activated, numerous things can happen. Some Trojans are more annoying than malicious. Some of the less annoying Trojans may choose to change your desktop settings or add silly desktop icons. The more serious Trojans can erase or overwrite data on your computer, corrupt files, spread other malware such as viruses, spy on the user of a computer and secretly report data like browsing habits to other people, log keystrokes to steal information such as passwords and credit card numbers, phish for bank account details (which can be used for criminal activities), and even install a backdoor into your computer system so that they can come and go as they please.

To increase your odds of not encountering a Trojan, follow these guidelines.

1 Remain diligent
T rojans can infect your computer through rogue websites, instant messaging, and emails with attachments. Do not download anything into your computer unless you are 100 percent sure of its sender or source.
2 Ensure that your operating system is always up-to-date. If you are running a Microsoft Windows operating system, this is essential.
3 Install reliable anti-virus software. It is also important that you download any updates frequently to catch all new Trojan Horses, viruses, and worms. Be sure that the anti-virus program that you choose can also scan e-mails and files downloaded through the internet.
4 Consider installing a firewall. A firewall is a system that prevents unauthorized use and access to your computer. A firewall is not going to eliminate your computer virus problems, but when used in conjunction with regular operating system updates and reliable anti-virus software, it can provide additional security and protection for your computer.

Nothing can guarantee the security of your computer 100 percent. However, you can continue to improve your computer’s security and decrease the possibility of infection by consistently following these guidelines.

The Advancement of the Keylogger

August 12, 2014 by  
Filed under General

A keylogger is a program that runs in your computer’s background secretly recording all your keystrokes. Once your keystrokes are logged, they are hidden away for later retrieval by the attacker. The attacker then carefully reviews the information in hopes of finding passwords or other information that would prove useful to them. For example, a keylogger can easily obtain confidential emails and reveal them to any interested outside party willing to pay for the information.

Keyloggers can be either software or hardware based. Software-based keyloggers are easy to distribute and infect, but at the same time are more easily detectable. Hardware-based keyloggers are more complex and harder to detect. For all that you know, your keyboard could have a keylogger chip attached and anything being typed is recorded into a flash memory sitting inside your keyboard. Keyloggers have become one of the most powerful applications used for gathering information in a world where encrypted traffic is becoming more and more common.

As keyloggers become more advanced, the ability to detect them becomes more difficult. They can violate a user’s privacy for months, or even years, without being noticed. During that time frame, a keylogger can collect a lot of information about the user it is monitoring. A keylogger can potential obtain not only passwords and log-in names, but credit card numbers, bank account details, contacts, interests, web browsing habits, and much more. All this collected information can be used to steal user’s personal documents, money, or even their identity.

A keylogger might be as simple as an .exe and a .dll that is placed in a computer and activated upon boot up via an entry in the registry. Or, the more sophisticated keyloggers, such as the Perfect Keylogger or ProBot Activity Monitor have developed a full line of nasty abilities including:

1 Undetectable in the process list and invisible in operation
2 A kernel keylogger driver that captures keystrokes even when the user is logged off
3 A remote deployment wizard
4 The ability to create text snapshots of active applications
5 The ability to capture http post data (including log-ins/passwords)
6 The ability to timestamp record workstation usage
7 HTML and text log file export
8 Automatic e-mail log file delivery

All keyloggers are not used for illegal purposes. A variety of other uses have surfaced. Keyloggers have been used to monitor web sites visited as a means of parental control over children. They have been actively used to prevent child pornography and avoid children coming in contact with dangerous elements on the web. Additionally, in December, 2001, a federal court ruled that the FBI did not need a special wiretap order to place a keystroke logging device on a suspect’s computer. The judge allowed the FBI to keep details of its key logging device secret (citing national security concerns). The defendant in the case, Nicodemo Scarfo Jr., indicted for gambling and loan-sharking, used encryption to protect a file on his computer. The FBI used the keystroke logging device to capture Scarfo’s password and gain access to the needed file.

Surfing the Web Anonymously – Questions to Ask

August 12, 2014 by  
Filed under General

When you surf the web it is possible to learn information about you even when you don’t want to advertise who you are. This is true even if your system contains no virus or malware software. Specifically information that is easily available online includes your IP address, your country (and often more location information based on IP address), what computer system you are on, what browser you use, your browser history, and other information. It gets worse. People can get your computer’s name and even find out your name if your machine supports programs like finger or identd. Also, cookies can track your habits as you move from machine to machine.

How do people get this basic information about you?

When you visit another web site, information about you can be retrieved. Basically, information is intercepted and used by others to track your Internet activities.

How do you stop this from happening?

First of all, it is possible to serf the web anonymously and thereby stop leaving a trail for others to find. Note that this is not fool-proof, but it makes it much harder for people to know who you are. There are products called anonymous proxy servers that help protect you. The anonymous proxy server replaces your Internet address for its own. This has the effect of hiding your IP address and making it much harder for people to track you.

How do I get an anonymous proxy server?

There are many vendors who sell anonymous proxy servers. There are also free proxy servers available to you. Two such products are ShadowSurf and Guardster. Guardster (http://www.guardster.com/) offers various services for anonymous and secure access to the web, some paid as well as a free service. ShadowSurf (http://www.shadowsurf.com/) ShadowSurf provides anonymous surfing at their site for free. Go to it and you will find a box to enter a URL that you want no one to track. There are many others, but here are two that are frequently used.

Another interesting product, given the recent news about the Google search engine filtering its findings for the Chinese government, is Anonymizer (http://www.anonymizer.com). This company, among others, recently (Feb 1st, 2006) pressed that it “is developing a new anti-censorship solution that will enable Chinese citizens to safely access the entire Internet filter-free” (http://www.anonymizer.com/consumer/media/press_releases/02012006.html).

Does an anonymous proxy server make you 100% safe?

No. Still, you are much better off if you use such technology.

What other things should I be concerned about when trying to keep my private information private?

Three other items come to mind when trying to keep your information private. First, you can use an encrypted connection to hide your surfing. This article does not go into detail on this, but search the web and you will find a lot of information on this. Secondly, delete cookies after each session. Third, you can configure your browser to remove JavaScript, Java, and active content. This actually leads to limitations, so you need to think about the cost/benefit of this course of action.

Anything else?

Wishing you happy and safe surfing!

Spam Buster

August 12, 2014 by

Spam. Nobody likes it. Nobody wants it. No, we aren’t talking about the canned meat, but those unsolicited, unwanted, irrelevant, or even inappropriate messages that hit our email in mass quantities. While most mailboxes have some type of spam filtering software built into their system, they never seem to do a very good job of catching what you want them to catch, and letting through what you want them to let through. Therefore, it becomes increasingly important to turn to some type of additional spam filtering product. One such filtering system, designed for Outlook and Outlook Express users, is receiving rave reviews for its superior detection and low rate of false positives (i.e,. what you want to get through does).

Cloudmark Desktop, formerly known as SpamNet and SafetyBar, uses a unique community-based filtering process. This community-based filtering system relies on users to report any new spam. Within minutes of a spammer being reported, they are placed on a blacklist. At that point, no other member will receive that particular spam. Cloudmark also applies the same basic process to phishing email scams.

What is interesting is how Cloudmark creates a digital reputation model of reporting spam. Each user starts with a neutral reputation. A user’s reputation will rise if they are among the first to identify undesirable content. On the flip side of the coin, a user’s reputation falls when they falsely reports spam. The result is a system that is automated, highly scalable and resistant to tampering.

An added bonus is that because the software doesn’t depend upon the user to configure its settings, it installs in minutes and is easy to use. Cloudmark blocks over 98% of spam from reaching your inbox and boasts over one million users worldwide.

The cost of program is $39.95 for a one-year subscription. The subscription is renewable annually. For those wanting to test drive the product, a free 15-day trial period for either your Outlook or Outlook Express is available.

Securing Your Computer System

August 12, 2014 by  
Filed under General

Today, more and more people are using their computers for everything from communication to online banking and investing to shopping. As we do these things on a more regular basis, we open ourselves up to potential hackers, attackers and crackers. While some may be looking to phish your personal information and identity for resale, others simply just want to use your computer as a platform from which to attack other unknowing targets. Below are a few easy, cost-effective steps you can take to make your computer more secure.

1 Always make backups of important information and store in a safe place separate from your computer.
2 Update and patch your operating system, web browser and software frequently. If you have a Windows operating system, start by going to www.windowsupdate.microsoft.com and running the update wizard. This program will help you find the latest patches for your Windows computer. Also go to www.officeupdate.microsoft.com to locate possible patches for your Office programs.
3 Install a firewall. Without a good firewall, viruses, worms, Trojans, malware and adware can all easily access your computer from the Internet. Consideration should be given to the benefits and differences between hardware and software based firewall programs.
4 Review your browser and email settings for optimum security. Why should you do this? Active-X and JavaScript are often used by hackers to plant malicious programs into your computers. While cookies are relatively harmless in terms of security concerns, they do still track your movements on the Internet to build a profile of you. At a minimum set your security setting for the “internet zone” to High, and your “trusted sites zone” to Medium Low.
5 Install antivirus software and set for automatic updates so that you receive the most current versions.
6 Do not open unknown email attachments. It is simply not enough that you may recognize the address from which it originates because many viruses can spread from a familiar address.
Do not run programs from unknown origins. Also, do not send these types of programs to friends and coworkers because they contain funny or amusing stories or jokes. They may contain a Trojans horse waiting to infect a computer.
7 Disable hidden filename extensions. By default, the Windows operating system is set to “hide file extensions for known file types”. Disable this option so that file extensions display in Windows. Some file extensions will, by default, continue to remain hidden, but you are more likely to see any unusual file extensions that do not belong.
9 Turn off your computer and disconnect from the network when not using the computer. A hacker can not attack your computer when you are disconnected from the network or the computer is off.
10 Consider making a boot disk on a floppy disk in case your computer is damaged or compromised by a malicious program. Obviously, you need to take this step before you experience a hostile breach of your system.
