Analysis: security weak spots

is136Reading the coverage of the recent breach of Adobe passwords, we learned that 1.9 million users used “123456” as their password. That’s right: out of 38 million cracked passwords, almost two million adults used ones more suited to five-year-olds.

Some of these people are corporate users – are they working at your company? Using Adobe products on machines attached to your corporate network?

I don’t want to horrify you, but a “rainbow table” is a cyberthreat you should know about, if only because it will motivate you to create strong, unique passwords every time a password is needed. It’s a precomputed table for reversing cryptographic hash functions, usually for cracking password hashes. In other words, a powerful tool the bad guys use to break into your accounts and steal your data.

Needless to say, cybercriminals don’t need precomputed tables to crack “123456.” Why waste time, when users make it so easy? And there are worse things out there – much worse.

Harden. Your. Weak. Points.

Security means more than “a firewall.” It means educating your employees – and ensuring that the corporate network is protected from a security threat you may not see coming: the disgruntled employee. According to Reuters, Edward Snowden persuaded his NSA colleagues to hand over passwords which he later used to download top secret material and leak it to the press. Sources said he told other staff he needed the information to carry out his job as a computer systems administrator.

Security is never “one-size-fits-all” and many enterprises now have a board-level CSO or CISO to oversee security policy. If your firm doesn’t have one, maybe now’s the time to think about budgeting for that position. And yes, you need a managed service (or device supported 24/7) to monitor and block malicious traffic up to the application layer.

Let’s ditch the infantilism of “123456” and take a look at some more evolved security strategies.

2013 trends

“With the increasing popularity of virtualisation and cloud technologies,” said APAC security specialist manager Andy Leung of Juniper Networks, “enterprises are using cloud-based applications and services, or moving some of their infrastructure to data centres.” Leung also said that BYOD is becoming part of standard business operations.

“Cybercriminals always look to exploit new vulnerabilities associated with the emergence and rapid growth of new technologies,” said Linda Hui, managing director, Hong Kong and Taiwan, F5 Networks. “It’s all been about apps, mobile, public cloud and big data in 2013 and this is where the new cyberthreats to enterprise security originate.”

“Mobile devices are getting infected, and sensitive data is being stolen via virus-riddled apps from unsanctioned mobile markets,” said Hui. “Organisations have little to no control or visibility into employee-owned devices and further issues are caused due to the blurring of corporate and personal data.”

“The top keys are always the same three things,” said Leung. “Increase employee productivity – such as BYOD initiatives. Improve the business by adopting more competitive strategies such as cloud. And control costs, with emphasis on decreasing opex – for example, a complete end-to-end security strategy that can be integrated seamlessly.”

F5’s Hui agrees. “It’s a perfect storm for enterprises,” she said, “having to fight new and increasingly complex cyberattacks brought on by a wave of technology transformations such as cloud and mobile while dealing with budget pressure.”

2013 concerns
“As enterprises move applications and infrastructure to cloud or data centres,” said Leung, “they’re concerned about service interruptions and data being compromised by hackers. We have seen increased uptake of security products that aim to protect Web-based applications and also defending Internet attacks like DDoS.”

“We’ve seen high demand for flexible, certified Web application firewalls and comprehensive, policy-based Web application security that can address emerging threats at the application level,” said Hui. “This combination significantly reduces the risk of damage to IP, data, and Web applications.”

Corporates open wallet for security
“Security, especially dealing with new challenges associated with mobile and BYOD, is definitely a priority spend despite resources being squeezed as businesses look for efficiency savings across the board,” said Hui.

Juniper’s Leung agrees: “We feel that the IT market is tough these days, but corporate spending in security is still increasing. As corporates invest in new platforms like mobile devices and cloud – which make business transactions more effective and ubiquitous -the need to protect and secure these channels are also important.”

“Organisations cannot be sloppy on cybersecurity as that will threaten the business with severe compromise from an operational or public relations perspective,” cautioned Hui. “Security spend needs to rise to deal with new and increasingly complex threats in an new IT environment infused with apps, mobile, public cloud and big data.”

Trends in 2014
“With adoption of new technologies like virtualisation, cloud, BYOD, or even SDN, enterprises need an integrated strategy to manage end-to-end security across their infrastructure,” said Leung. “A security breach in any part of their operation-chain can be disastrous.”

“A comprehensive, multi-layered security approach is best to mitigate cyberattacks,” said Hui. “For an effective defense against cyberattacks, enterprises should have the following covered in their security framework: access layer, application layer, network layer and compliance.”

“If enterprises still manage their security in individual silos, opex is a burden for the operation,” said Leung from Juniper. His simple advice for enterprises: plan out an integrated security strategy ahead of time.

“The continued mass adoption of SaaS, mobile and big data-infused public cloud IT programs will be the biggest market challenges in 2014,” said Hui from F5. “This will result in an increasingly dispersed organisation and one that is harder to securely manage. Users, devices, applications and data centres are now often located outside the traditional business perimeter, and the growing complexity of managing access and authentication puts an ever increasing burden on IT infrastructure and management costs.”
