Privacy Awareness Week – Computer Protection Tips
This week is ‘Privacy Awareness Week’ 2010 and as such it is urged that we familiarise ourselves with our rights, 
obligations and best-practice in relation to privacy.
The few recommendations below, from the Office of the Privacy Commissioner of Canada, are related to Computer identity and information theft. They are well worth reading through:
- Make sure your computer has firewalls, virus protection and online security and privacy safeguards.
- Your online accounts should only be accessible with passwords that you create and change often. Your passwords should be hard for anyone to guess.
- When you shop or bank online, or fill out online forms, look for the padlock symbol at the lower right corner of your screen. This symbol means the information you provide is secure.
- When you log on to your e-mail or bank account from a library or other public computer, make sure no one can watch over your shoulder as you type in your password and other private information. Log out when you leave.
- Be careful about any personal information you divulge online, including in chat rooms and over social networking sites such as Facebook and Twitter.
- Be suspicious of e-mails that appear to come from financial institutions or government agencies, asking you to provide personal information online. Real banks and governments don’t do that, but scammers will often hijack real logos to make their fraudulent messages look authentic.
- Delete any e-mail soliciting funds unless you can verify independently – for example with a phone call – that it’s from a reputable organization.

P.S. I’m fully aware that there are some noticeable omissions from my list such as Linux, OpenOffice and Google Docs 
5 Steps to Protect against Malware
Malware is a generic term for I.T. related security issues such as phishing, viruses, Trojans and other harmful and unwanted I.T. activities. Malware infection is very widespread and the method of attack is constantly 
evolving and becoming more sophisticated. Internet crime (of which security is the central pillar in the fight against this type of crime) is very big business and is worth billions of dollar per year to organized crime syndicates. Unfortunately many businesses view security threats as purely tangible i.e. an alarm will be fitted at physical locations and physical assets insured. Cyber crime however can be far more detrimental to a business; how would your customers react if cyber criminals attained their credit card details from your computer and sold them Online?
Here are five simple tips to increase your I.T. security. Fortunately there is usually no need to buy I.T. security software as the free software is just as good as paid-for software:
1. Install and use Anti-Virus SoftwarePaid-for Anti-Virus, Anti-Spyware and Internet security software such as MacAfee and Norton are commonly used and are typically good products. Often however the costs of the products are expensive which discourage use and updating the software (and virus definitions). Fortunately there are a few very good competing products which are free to use and update (check licensing conditions of these products to find out if free use applies to you); AVG is excellent and Microsoft Security Essentials is new and getting rave reviews.
Of course, anti-virus and anti-spyware products are only useful is they are kept up-to-date and are used!
2. Install and use a FirewallQuite simply, a firewall detects communication to or from your computer which is irregular and is typical of Malware. Much Malware is intended to gather and send data from an infected computer to the cyber hacker (e.g. credit card details). A Firewall attempts to detect and block this malicious transfer of data. Windows Firewall is included with Windows XP and Vista and is very effective. There are also numerous paid-for Firewalls however they are unlikely to offer any benefits over the free offering from Microsoft (i.e. Windows Firewall).
3. Update SoftwareEffective software developers are constantly updating software to be more secure. It is therefore essential to keep software updated. Some updating of software may be automated (such as Windows Updates and anti-virus updates) however the need to update other software may be difficult to detect. Fortunately there are free Online and software resources available that advise which software needs to be updated and will make updating more simple. One of these resources is Secunia; a scan will note what software needs updating and a link to the update is provided.
4. Secure Email and Internet AccessEmail is the most prolific means of spreading malware. Most of us receive significant volumes of spam of which numerous are of ill intent. Fortunately most good email providers (including Hotmail, Gmail and Yahoo Mail) provide junk-mail and spam filters. Ensure however that your email provider is providing a level of protection against illicit emails. Above all it is important to be conscious that cyber-criminals are attempting to gain access to your computer through email (awareness of security issues is discussed later in this article).
Internet Browsers (e.g. Internet Explorer and Firefox) have built in security which is effective however nothing replaces caution when it comes to Online security. Fortunately the major search engines don’t display known malware distribution sites and further Online security may be attained through the likes of AVG free edition (as discussed previously where every page visited is checked for malicious content.
5. Be AwareBeing conscious of the threat of I.T. malware is the most beneficial means of avoiding cyber-criminal activities. Stay up to date with security threats by reading articles on good quality computer security sites such as StopBadware. Most of all however always remain diligent and cautious and do not open files from unknown email addresses nor give away personal information online unless you are able to verify the requester.
The spread of Malware is at an all time high. Protection against Trojans, anti-spyware and other malicious content can mostly be defended against with free software. Don’t let your business be negatively affected through malware (if the head of the FBI can fall victim to cyber-crime then chances are, so can you).

Related postsTwitters Security Nightmare
The 140 character limit in Twitter combined with its incredible success has been welcomed by phishers, spammers, Trojan and virus developers and other malicious content providers (we’ll call them ‘malware’ in this article).
As most Twitter users know, URLs are typically shortened using URL shorteners such as Bit.ly (which also powers j.mp) and Tr.im (which is now open-source) so as to minimise the number of characters used by the URL. For example, the URL http://eckstein.id.au/1566/management/leica-kgb-nsa/ is shortened as http://br.st/0io using Br.st, a free URL shortening service.
Why Spammers Love TwitterUnfortunately, the shortened URL does not indicate anything about the full URL to which it redirects. Research by the security software company Mcafee has shown that 1 in 5 of ‘.hk’ top level domains (TLD) is rated as risky to access while 1 in 10 ‘.cn’ domain names is likely to contain malware or other suspect content. By contrast, ‘.gov’ and ‘.jp’ websites are extremely unlikely to contain malware. URL shorteners mean that we become unaware of the TLD of the URL. Malware distributers love Twitter because a URL can be masked so the viewer is unaware of the TLD (i.e if we knew that a URL ended in .hk we’d think twice about visiting that URL but a shortened URL doesn’t show the .hk).
The additional danger is that it is possible for blacklisted URLs to bypass security in browsers and security software by using shortened URLs. Great strides have been made over the years in collecting data about insecure websites. Google, Bing and other Search Engines exclude blacklisted sites from Search Engine Results Pages (SERPs). Most good Internet browsers also detect and block blacklisted URLs. The problem with shortened URLs is that they mask the original blacklisted URL so can, and often do, bypass Internet security software and blacklists.
How Malware spreads in TwitterThe free and instantly generated nature of URL shortening services is perfect for phishing, spamming malware and Trojan distributers. All a malware distributors need do is create a short URL and post a catchy and popular ‘tweet’ with the shortened URL. Due to the highly interactive nature of Twitter, it is likely that someone will visit the tweet and will likely click on the link. This is far more simple and effective for malware distributors than spamming or creating websites and relying on Search Engines to drive traffic to their malware spreading sites. In addition, once it becomes known that the short URL is a security risk all the malware distributor needs do is create another free short URL and another catchy and topical tweet; in a matter of a minute the malware distributor has a whole new audience who are unaware that s/he is a security risk.
How to be Twitter Security AwareCertainly, Twitter security vulnerabilities have been widely publicised however the average user still appears unaware of the need to be wary of shortened URLs in anticipation that they may be links to Trojans or other malicious content. It is more important than ever to use online security software as well as keep Internet Browser and operating system software up to date.
