Becoming a Consultant

How to be a security Consultant?

http://www.shvoong.com/writers/razvi

We ( I ) dream of being our (my) own boss, but what does it take to set up a successful business in the real world?

IT security consultants have it easy, as everyone knows. They swan around the city, taking long lunches and even longer holidays, and all for a few meetings, a couple of phone calls and a bit of fiddling around with a BlackBerry. And anyone with some idea about IT security could do this, right? Well, not exactly. Let’s takes a look at the life of an IT security professional going solo, how it’s done, and the highs and the lows.

First, setting up on your own isn’t the right job for everyone. While a large corporation has a department working on each business area, such as IT, marketing, accounts etc, the lone consultant has to take on all these roles, and more. Being a qualified and experienced IT security professional does not necessarily mean an individual can deal effectively with clients, construct and follow a realistic business plan and stick to their own budgets.

“The biggest challenge is to have the combination of required capabilities,”"A technically superior IT professional will also need excellent marketing and personal skills to succeed on their own. It’s all about the nature of the person - a techie guy who communicates through his keyboard is unlikely to be able to present at board-level. We’re talking about business here, so having and adhering to targets, whether performance-related or financial, is crucial. This is a very rare combination, but it is possible to learn these other skills, especially on the business side.”

“You need to be able to approach the entire board convincingly and lucidly, and do the same with the IT department. You have to be comfortable discussing the business case for a job and proving return on investment,” “ it’s important to be able to move customer thinking away from IT as a grudge spend and towards recognising the potential of new technology and ways of working.”

The right qualifications

A consultant also needs to have the raw industry knowledge and the credentials to go it alone. Several years of top-level security experience are critical, as well as specific qualifications. “There are a lot of qualifications to choose from, and there are multiple ways to refine or broaden the focus of your business through taking management or architecture units, for example,” “Establishing relevant and high-quality credentials upfront is the most important area of setting up a consultancy.”

The most widely recognised formal qualifications include those from ISACA (the Information Systems Audit and Controls Association), (ISC)2 (the International Information Systems Security Certification Consortium) and ISEB (the Information Systems Examinations Board). These certifications are globally recognised, a key factor when working with international organisations.

The two most relevant ISACA qualifications, both accredited by the American National Standards Institute, are the CISA - Certified Information Systems Auditor, and the CISM - Certified Information Security Manager. (ISC)2 recommends the Certified Information Systems Security Professional (CISSP), which is accredited by ANSI to ISO Standard 17024:2003. Within this qualification, either the Information Systems Security Architecture Professional (ISSAP) concentration or the Information Systems Security Management Professional (ISSMP) are of most use to freelancers, according to the company.

However, not everyone agrees with this emphasis on education. “Surprisingly it has been found that customers often don’t want to look at qualifications as much as get references for similar work done. Good-quality references are the most important thing to convince customers to take you on.” “You need to be careful about references, and be sure to keep jobs quite separate. The client is not stupid, and if you talk openly about previous work, you can be sure they will be wondering what you will say about them in the future.” Relationships are key to establishing a successful consultancy, but they can also be the biggest challenge. Vendors will be keen to get you signed up to an exclusive deal, while customers will expect you to have wide-ranging knowledge to call upon, as well as having in depth information at your fingertips. So is it better to stay independent or commit to one vendor? “It’s important for consultants to remain independent from vendors,” “You need to partner with them, but not get sucked in further. This can be a bit of a love-hate relationship, as they’ll be keen to pull you in - it can be a delicate balancing act. It is key that you can recommend the appropriate solutions to your clients - bear in mind that the security market changes every two years, so you’ll need to keep up to date.”

Many IT security professionals will come from a background of working with blue-chip companies and should have a pedigree spanning several in order to succeed. “Having set up your own consultancy, you have to reposition your ‘brand’ as separate from your last employed post. This can easily lead to conflicts of interest, which you must be very aware of. Additionally, working with competitors to your ex-employer needs to be kept on a very professional footing.”

Finding the right balance

The most important relationship is that between client and consultant, and again you need to watch out for potential pitfalls. While a consultant should provide value for money, there’s also the issue of giving too much. Essen believes that security audits are a good example. “Some companies with their own IT department are a tricky balance to strike, especially when you’re doing an audit,” “Too much information and they could just implement your suggestions themselves, while too little loses you the work. It’s not always easy to manage how much detail to give.”

Marketing is a tricky area even in established businesses and can easily trip up beginners. Selling yourself too aggressively may alienate customers, or could simply be so successful that you’re inundated with more work than you can do. An added danger of this unbalanced “boom-and-bust” way of working is that it may lead to dry periods when little money is coming in - a real risk for a small business.

So what can IT consultants do to market their offerings in the right way? “Being known in the security field is vital for marketing and business purposes, and an excellent way to raise your profile is by speaking at conferences,” “But make sure they’re targeted at the right market. RSA and Infosec have both been good for me in the past - it’s important to go along and meet the right people. Word of mouth is the best recommendation, and the biggest winner for smaller businesses without a big public profile - you have to make your reputation travel.” “Recommendations are the number-one sales generator. Your reputation will spread itself to a certain extent - you have to ensure that it’s totally spotless, and keep it that way.”

Of course, it’s not just about going it alone whatever your skills. The most successful businesspeople know their own strengths and weaknesses, and play to them. If you don’t have the marketing abilities you need to make IT security consultancy work, then find someone who does. “Partnering with ‘the other half’ is often the most successful way to begin a business,” “It’s all about strengths and weaknesses, as well as self-knowledge.”"You simply have to have a business head to set up on your own. A degree or further qualification in business studies is a good idea, but it’s always difficult to switch between different hats, and it’s important to be able to relinquish parts of the workload to others.”

Naturally, there are benefits to running your own IT security consultancy, such as personal fulfilment, flexibility and job satisfaction. There is also a very practical side. In spite of the consolidation of the security market and moves by giants such as IBM to provide localised consulting services, there is still a large gap in the market for smaller businesses. “The largest consultancies are keenest on bigger projects, purely due to their size, so smaller companies can simply pick out the smaller jobs,”Also, a smaller consultancy can specialise more readily, a move that makes particular sense for the consultant going solo. Setting up a stand that has a fresh, new unique selling point in a fairly crowded market could be the only way to be successful. “The biggest error people can make when considering whether to go it alone is to wait for the best moment to do so - it never comes! It’s certainly better to do it younger, as you can then change your plan more easily. Leave it too late and you might be too old to re-enter business.”

Ultimately, becoming a lone IT security consultant is a long task, and not one to be taken lightly. Without careful, realistic planning and solid business acumen most startups will fail, and you need the right mix of personal attributes to avoid disappointment. For those entrepreneurs who succeed however, it will be the most fulfilling thing they ever do …

Image Encryption Assignment

This is an interesting assignment set for postgraduate students in the field of ICT. The work is based on the analysis of AES-Rijndael and RC6 block ciphers for digital images. Here are sample abstracts of their work, your comments are welcomed. Detail assignment papers are provided upon request.

By Hemraj Ramsurrun

Visual inspection is not sufficient to analyse the encryption
efficiency of a given algorithm. This paper describes three main
mathematical models: Maximum Deviation, Correlation
Coefficient and Irregular Deviation, as proposed in [1] and [2],
used to evaluate the encryption quality of the RC6 and AES
Rijndael block ciphers when applied to digital images. These
models are centered on the fact that encryption brings a change in
the pixel values of the images and exploit this change to judge
quality of encryption. The results are quoted from the two
reference papers based on which, a few observations are made.
AES Rijndael and RC6 were applied in three modes of operation
namely: ECB, CBC and OFB. It was found that both RC6 and
Rijndael offer good encryption quality with Rijndael being
slightly better. The results obtained in the ECB mode were found
to be less interesting while the Irregular Deviation measuring
factor proved to be most efficient to assess encryption quality.

By S. Ramsaha

The main objective of this work is to study the
encryption efficiency of AES Rijndael algorithm for digital
images by comparing it to RC6. Firstly, the importance of
image encryption is emphasised followed by a review of
Rijndael and RC6 algorithms. Different Bitmap images are
encrypted using the two algorithms based on electronic code
book, cipher block chaining and output feedback modes. The
encryption efficiency is then evaluated based on metrics like
maximum deviation measuring factor, correlation coefficient
measuring factor, irregular deviation measuring factor. Also,
other important metrics like encryption time and throughput
are considered.

By Shobna Jadunundun

Encryption is the most trusted practical security technique to protect users‟ sensitive data especially for multimedia transmission. Consequently, several algorithms have been developed; RC6 and Rijndael being among the most popular. To verify the encryption quality of these two algorithms when applied to different types of bitmap images for example, visual inspection alone is insufficient. Hence, three measuring factors have been considered based on the fact that encryption brings an irregular change in the pixel values of an image. These are Maximum Deviation, Correlation Coefficient and Irregular Deviation and have been used to evaluate the encryption quality of the two block ciphers operated under three modes namely: Electronic Code Book, Cipher Block Chain and Output Feed Back. Discussion of results is taken from those given in papers [1] and [2] and some recommendations have also been suggested. The observations made show that CBC and OFB are better than ECB in hiding image features. Irregular deviation can be used as the only metric to evaluate encryption quality as the results obtained are more conclusive than those of the other two metrics.

Majority of users leave their wireless networks exposed

Nearly 55% of businesses are leaving themselves vulnerable to hackers by not taking simple steps to protect their wireless networks, according to new research. Among the protocols used by businesses to protect their wireless networks, it is found that 40 per cent use the largely-ineffective wired equivalent privacy (WEP) protocol; staggeringly, 15 per cent use no protection at all.

The research also highlighted a similar lack of security awareness among home users. Forty-eight per cent use the WEP protocol, while 10 per cent use no protection. It is widely acknowledged in the security industry that the WEP protocol is being depreciated as it can protect only against hackers with the most basic programming knowledge. WEP encryption can be hacked in minutes by a determined blackhat with the requisite skills and software.

All home users and businesses are urged to check their configurations and switch to the wi-fi protected access (WPA) protocol. WPA affords home users and businesses a far higher level of security, as it uses a sophisticated key structure that creates new encryption keys as the system is used. This, along with other enhancements provides improved protection and is able to counter successfully the established key recovery attacks on WEP.

As a researcher in the field of wireless security it is known that: “WEP is no obstacle for a shrewd hacker and can be sidestepped in minutes. By configuring wireless networks to WPA, businesses and home users immediately make any hacking attempt significantly more difficult. And the good news is that switching from WEP to WPA typically involves only the flicking of a switch.”

War of the Airwaves

As new wireless standards are being adopted, the next generation of wireless security tools are being developed to combat ever-changing threats. Wireless deployments are moving from pilot, to production, to mission critical. However, the bad news is that more wireless devices means more hackers exploiting the vulnerabilities of wireless LANs. Wireless has become the new attack frontier. Tools that are currently being used to attack wireless networks include WEP cracking, exploitation of authenticated clients in 802.1x environments, interception of authentication credentials etc. New stealth tools are being designed to bypass many security measures making the attackers invisible to the network and its defenses. This makes most firewalls obsolete and leaves devices exposed, allowing attackers to send and manipulate data and exploit devices at will. These efforts are well organized, well financed and intensely motivated leading to a dangerous onset of organized crime. This is the “War of the Airwaves”.

Video Blogging - Vlog

Video blogging, sometimes shortened to vlogging is a form of blogging for which the medium is video. A vlog (or video blog) is a blog that contains video content. The small, but growing, segment of the blogosphere devoted to vlogs is sometimes referred to as the vlogosphere. Some bloggers have included video content for years. However, vlogging is becoming more common as equipment becomes cheaper and supporting software and hosting and aggregation sites become more prevalent. Both Yahoo and Google feature video sections and many MP3 players, such as the hugely popular iPod, support video.

Anyone with access to a video-capable camera and a relatively recent computer with a high-speed connection can create a vlog and publish and distribute it online. Here’s how:

  1. Make your video and save it as a file on your computer. You can use easily available software, such as Windows Movie Maker, QuickTime or iMovie (for Apple systems).
  2. Compress your video file. Movie Maker, iMovie, Avid Free DV and Final Cut Pro are among the programs you can use to do this.
  3. Set up a blog. Feedburner and Blogger.com are popular blog hosting sites.
  4. Make a screen capture of an image from your video to display in your blog.
  5. Get your actual video content published online. Internet Archive, BlipTV and OurMedia are free hosting services.
  6. Create your blog entry. Add the image and link to your video.
  7. Get an RSS feed with enclosures and publish your blog at Feedburner or a similar site.

The vlogosphere is a very democratic arena. Unlike mainstream media, such as television or commercial Web sites, vlogs are not, for the most part, created to make money. As a result, vloggers are free to make their content about whatever they desire, no matter how controversial or esoteric the topic. Vlogging gives average citizens an audience and a chance to make their voices heard. In a BBC News article called “The year of the digital citizen,” Jo Twist discusses the potential of vlogging and podcasting to provide a venue for public discourse: “The changing nature of news offers a diversity of voices, sources, and choice… and lets anyone join in global and local conversations.”

Viral Video Marketing

Most viral and entertaining videos on the Internet.

The term viral video refers to video clip content which gains widespread popularity through the process of Internet sharing, typically through email or IM messages, blogs and other media sharing websites. With nearly 70% of home Internet users now surfing using a broadband connection, online video viewing has exploded. Video sharing site YouTube has become a virtual overnight sensation and major search engines Google and Yahoo soon followed with their own video sharing sites. Like YouTube and Google Video, many of the video sharing sites allow visitors to paste videos into their own websites and blogs, effectively extending the reach of your video.

In a February 2006 article in the New York Times, Julie Supan, YouTube’s marketing director said the site had more than 10 million videos viewed daily. “We’re streaming 115 videos a second,” she said, “6,944 per minute.”

And people aren’t just watching video online, either. They’re taking it with them by downloading video clips to their handheld devices like the video iPod and Sony’s handheld video game console, the PlayStation Portable. That allows them to share your video with others, extending your message even further…offline. This habit will only grow as more and more cell phones have the ability to play and/or stream video.

What Is Video Advertising?

VideoJug present a short guide to Video Advertising. The popularity of online video in recent years has led to online video Advertising an increasingly attractive proposition for marketers. Here it is explained.

With broadband take up at an all time high of 89% of online users, faster speeds and improving quality of experience is already upon us. Increased broadband use and speeds allow for the effective targeting of
specific consumer groups for adverts, with the added bonus of advertisers being able to track, when and for how long each of their films has been viewed by consumers. Which is why video advertising is such an attractive proposition for those companies looking to maximise their marketing budget.

Video advertising online can appear in a variety of formats to suit every product - Banners on sites, pre roll and post roll video ads, as well as a range of new interactive units such as YouTube’s new overlay format, offering the consumer the opportunity to interact. Another exciting development in video marketing is
