6 Tips for Getting to Grips with Data Security using FDE and FLE

August 13th, 2015

If FDE and FLE sound like twins to you, you could be on the right track for a comprehensive approach to keeping your data confidential. Indeed, FDE (full disk encryption) and FLE (file level encryption) both have security advantages to offer on their own – and even more when they are used together. Conversely, this means that neither encryption approach replaces the other. In particular, FDE protects data at rest on a PC hard disk, for example, whereas FLE protects data in motion, as in files that are being transferred or copied to other systems. Both can benefit from paying attention to the following.

Why You Should Keep Doing IT Penetration Testing

August 11th, 2015

Like a medical examination, the result of penetration testing to assess your organisation’s IT security is technically only valid at the moment it is performed. Independently of how thorough such ‘pen tests’ are, the context in which they are performed changes on a frequent basis. IT hardware and software vendors release new versions and patches of firmware, operating systems and applications. Hackers invent new attack vectors. Employees come and go, and business partners and suppliers, with whom you collaborate and share information, change too. If the business and IT environment fluctuates so much, why then is it still important to do penetration testing?

The Future Economy of Continuity

August 6th, 2015

The future is automation, business processes automated, IT systems automated but where does that leave us humans in the equation of the automated world? And will there be sufficient job positions to counteract the imbalance of jobs moving to an automated cycle? The answer lies within our economy and heads of organisations. For a business to progress and effectively make their margins and profits every year involves many factors and the biggest factor is the expense of paying employees.

Making Business Continuity Standards a Requirement

August 4th, 2015

We always tend to leave the ground up requirements astray and why? Because they’re not necessary or require too many resources to maintain but what happens when that requirement becomes a legal requirement which is enforced by law will not allow you to run your business without having it. Like leaving breakfast aside and having only lunch and dinner, why would you miss a meal if you know it might affect your body mentally and physically and that goes without say to your Business Continuity Plans (BCPs), without them there will be no BC controls and best practices in place.

The Cloud Experience

July 30th, 2015

For many years we’ve been hyped with the cloud generation of computing with the likes of giants such as Amazon, Microsoft, VMware and Oracle to name a few in the ring. But moving entirely to the cloud has some considerations to take into account and a Cloud Risk Assessment is to be conducted to analyse the possible risks you may be placing your data in. On the up side cloud reduces internal costs, internal resources providing companies with better efficiency and flexibility to maintain data usage loads and scalability.

How Are You Doing with Your Android Security?

July 28th, 2015

Every once in a while it’s good to take stock of a situation. A projected 1.25 billion Android users for 2015 (according to Gartner) is such a situation. Either your organisation is already an Android shop or it is likely to become one in the near future. A plethora of software apps for the Android OS and a decidedly spotty security record for many Android users means that reviewing your approach to Android security could be a wise move as well.

IT Network Firewall Technology is a Model for Business Continuity Too

July 23rd, 2015

One of the bugbears of IT network security is the denial of service (DOS) attack. Instead of (or as well as) trying to sneak past a firewall with a few innocent-looking data packets, the DOS attack tries to cripple a network or a system by swamping it out. In the case of network firewalls, the attacker will try to generate as much network traffic as possible to overload the firewall’s processing power. Attackers often multiply the sources of the network traffic for that reason, leading to distributed denial of service (DDOS) attacks. Firewalls that are submerged by traffic may become unmanageable, unless the vendor has taken suitable design precautions, which might also inspire good business continuity in general.

Middle East Respiratory Syndrome – Is Carelessness or Ignorance the Bigger Problem?

July 16th, 2015

Middle East Respiratory Syndrome (MERS) is a new threat for humans. Also known as ‘camel flu’, it is a viral respiratory illness first identified in 2012 in Saudi Arabia, where so far it has caused over 280 deaths. Since then it has spread to other countries. As of late June 2015, South Korea was the second most affected country, with 31 fatal casualties. People infected with Middle East Respiratory Syndrome coronavirus (MERS-CoV), to give it its full name, develop fever, coughing and shortness of breath. Although the symptoms are recognisable, the transmission of the virus has yet to be properly understood.

A Marketing Lesson in the Debate about AES 128 and AES 256 Encryption

July 14th, 2015

For business executives and marketers, as well as IT departments, the following paragraphs on the secrets of cryptography hold a useful lesson. First a quick recap on what this is all about. AES stands for Advanced Encryption Standard, used to keep your data confidential. The 128 and 256 numbers refer to the size of the ‘key’ that is used to encrypt your data and then to decrypt it so that you can use it again. In an intuitive marketing sense, 256 should be significantly better or ‘stronger’ than 128. This sounds good, but is it of any practical use? Or is it simply fulfilling a psychological need rather than a technical one?

Image Backups Help You Get Back in Business Faster

June 30th, 2015

What does it take to get PC or server backups to work properly and bring computers back to operational status? Correctly stored data files are a critical component for most organisations. However, on their own they won’t let you get back to business. You’ll also need the applications that generated those data files and you’ll need the associated configuration and profile information. That includes user and account-specific information and any purpose-built software modules to link your system to others in your enterprise. The smart solution would be to back up all of this information within the same process.

Backfiring Data Encryption or Being Hoisted by Your Own Petard

June 25th, 2015

Data encryption should be a good thing for security. When your data is encrypted using today’s encryption standards, other people cannot decode your files or your information. Data at rest encryption (DARE) takes care of the data sitting on hard drives, while data in motion encryption (logically DIME – you read it here first!) ensures that it remains confidential while being transmitted from one point to another. However, like the petard or bomb that blows its user up, encryption can sometimes backfire.

Teachers and Role Models Falling Down on Disaster Recovery

June 23rd, 2015

When it comes to singling out sectors that are in the forefront of disaster recovery, finance is often quoted as an example. With so much depending on the ability to recover systems and data rapidly after any incident, major banks were among the first to implement hot failover data centres for instance – as well as being among the only organisations that could afford them. At the other end of the scale, there are those that are particularly ill-equipped to deal with IT disasters. The education sector has been identified as one example, but another group falling short of the levels required could surprise you.

Risk Management for the Masses! Or At Least For Each Project…

June 18th, 2015

Risk management is one of those areas that are too often “somebody else’s responsibility”. Whether through lack of knowledge or indifference, it gets shunted off somewhere else and replaced with an approach of “it’ll be alright on the night”. Unfortunately, it frequently isn’t. Like business continuity or information security awareness, risk management should ideally be everybody’s business and accepted by each member of an organisation as an individual as well as a collective responsibility. Risk management on a per-project basis can help move the needle in the desired direction.

Data Loss Prevention and the Insider Twist to IT Security

June 16th, 2015

For many people, IT security is about keeping the bad guys out of the data centre by using firewalls to control external access and anti-malware programs to prevent hackers from infecting servers. That is only half the picture however. The threat that has also been growing comes from people already within the security perimeter of the data centre. They have legitimate access to servers, but are misusing that access either unintentionally or deliberately to take data out. The challenge in resolving this kind of insider threat is that it is typically not a malware attack, but a personal ‘manual’ attack.

Look Who’s Doing Risk Management

June 11th, 2015

If you’re wondering how much risk management should become part of your organisation’s rulebook, you may already be looking around to see who else is doing it. Insurers and bankers are obvious examples, because their businesses are centred on risk calculation, whether in terms of setting insurance premiums or defining credit interest rates. Many insurers are also ready to discuss risk management with potential customers in a variety of different industry sectors. These can range from agriculture and aviation to sports and transportation. However, there are other perhaps unexpected examples that show how far the concept of risk management has spread in general.
