BYOD

Recently, I attended a security seminar on the newest buzzword in the IT industry – BYOD, or Bring Your Own Device – to complete my CISSP CPE (Continuing Professional Education) requirement for the year. The seminar was sponsored by ISC2 and the speaker, Brandon Dunlap, is a seasoned, insightful, and very entertaining speaker.  I highly recommend the seminar.

BYOD came about because of the popularity of mobile devices – iPhone, iPad, Android, Blackberry, etc.- , the consumerization of IT, and employees getting more flexible schedules.    Companies are starting to allow their employees to use their own devices – to improve productivity, mobility, and supposedly save the company money.  The millennials, in particular, are more apt to use their own devices.  Owning these devices for them signifies status symbol or a fashion statement.

However,  does it make sense to allow these devices into the company’s network?  What are the security implications of the BYOD phenomenon?

From a technology standpoint, there are a lot of innovations to secure both the mobile devices and the company’s applications and data, for instance, using containers, to separate personal apps and company’s apps.  Security companies are creating products and services that will improve the security of BYOD.  But from a policy and legal standpoint, very little is being done.  Companies who jumped into this BYOD buzz are getting stung by BYOD pitfalls as exemplified by one of the greatest IT companies in the world – IBM.   In addition, recent studies showed that BYOD does not really save company money.

Companies need to thoroughly understand BYOD before adopting it.  It is a totally new way of working.

The seminar highlighted the many problems of BYOD, and the immense work that needs to be done to make it successful.  No wonder the organizer entitled it “Bring Your Own Disaster” instead of “Bring Your Own Device.”

 

Security Strategy

Amidst the highly publicized security breaches, such as the LinkedIn hacked passwords, hacktivists defacing high profile websites, or online thieves stealing credit card information, one of the under-reported security breaches are nation states or unknown groups stealing Intellectual Property information from companies such as building designs, manufacturing secret formulas, business processes, financial information, etc. This could be the most damaging security breach in terms of its effect on the economy.

Companies do not even know they are being hacked, or are reluctant to report such breaches. And the sad truth is that companies do not even bother beefing up their security until they become victims.

In this day and age, all companies should have a comprehensive security program to protect their assets. It starts with an excellent security strategy, a user awareness program (a lot of security breaches are done via social engineering), and a sound technical solution. A multi-layered security is always the best defense – a firewall that monitors traffic, blocks IP addresses that launches attacks, and limits the network point of entry; an IDS/IPS that identifies attacks and gives signal; a good Security Information and Event Management (SIEM) system; and good patch management system to patch servers and applications immediately once vulnerabilities are identified, to name a few.

Cost is always the deciding factor in implementing technologies. Due diligence is needed in creating cost analysis and threat model. As with any security implementation, you do not buy a security solution that costs more than the system you are protecting.

Thoughts on Information Security

I cannot stress enough the importance of information security. Almost everyday we hear stories about security breaches – hacker groups defacing websites for political purposes, countries stealing proprietary information from other countries and companies, organized crime stealing credit card information and selling those in the black market.

Cloud computing and mobile devices have exacerbated the problem.

The thing with security is that it is at odds with convenience. We want to get things done quickly, but security slows us down. For instance, we are required to enter hard to guess passwords to access our bank account online or access our company’s applications. Why not just let us in right away? Remembering passwords (and lots of them) and being required to change them every three months take some time and effort.

But if we want ourselves and our companies we work for to be secure, we should give up a little convenience. There is no other way.

A lot of technical solutions and innovations have been devised to improve information security. But no amount of technical innovation can solve the weakest link in security – social engineering. Remember the “I Love You” virus several years ago? It was a virus that was spread when you open an email with the subject line “I Love You.” Who wouldn’t want to open an email with that subject line?

User awareness is the key. Companies and individuals should at least invest in training on security and privacy.

The sad thing is that many companies and individuals do not take security very seriously, until they become victims. True, we should not spend significant amount of time and money for security. The resources we spend on security should be proportional to the assets we are protecting. You should not buy a 1 million dollar vault to protect your 100K painting.

When I obtained my CISSP certification several years ago, I didn’t plan on specializing on information security. I have, however, incorporated good security practices in system and network design and implementation, virtualization, storage, and almost all aspect of IT. But with the tremendous need for IT security professionals these days, I might consider specializing in information security.
