When was the last time you assessed your cybersecurity strategy? Given the ever-changing security landscape, it’s probably been too long. Businesses can’t afford to be complacent. Yet, despite the near constant stream of data breaches making headlines, far too many organisations insist that their current security model is good enough, writes Dan Panesar, VP EMEA, Certes Networks.
You’ve never been hacked before, and you’re confident you know where you critical or sensitive data is at all times. Why change something that’s working today?
No business can ever be sure where its data is or that it hasn’t been compromised in transit. Failure to recognise this issue is a board-level responsibility. You tick the boxes when it comes to GDPR, PCI DSS, HIPAA (and other regulations) so you’re secure. No company that has met their compliance requirements has ever been hacked, right?
Taking a compliance led approach to securing customer data will cause a fundamental vulnerability within the cybersecurity infrastructure, simply waiting for hackers to exploit. Compliance is important, clearly, but it should be a subset of the overall, continuously evolving security strategy, rather than an end-point goal in itself.
Organisations are understandably concerned about the financial penalties associated with failing to achieve regulatory compliance. But take a step back and consider the financial implications of a data breach, of high profile customer data compromise. That is a far more significant cost and an event that will have long-term repercussions on customer perception and loyalty.
You’re happy that your WAN provider has the necessary controls in place to keep your data secure as it moves between your locations. They said you could trust them, so why wouldn’t you?
WAN providers can’t guarantee the security of their environments, and the security of your data is ultimately your responsibility. What’s needed is a security-first ‘Zero Trust’ mindset that protects data before sending it to the carrier network.
Your board is telling you that IT costs need to be reduced, so the easiest thing is to cut the security budget; it reduces cost without reducing functionality. But, just in case, you increase your Cyber insurance coverage.
Cyber-Security insurance policies require customer diligence. You cannot buy a security policy, not deploy security and then expect a post-hack payout.
More significantly, think about the cost and loss of earnings associated with the fallout of a data breach…..
Now rethink cutting your security budget.
Your network is secure so you don’t need to secure your data in motion. After all, you own the entire infrastructure end to end, wherever your data goes.
When 70% of all breaches are as a result of internal user compromise, this is a false sense of security.
Not only are current security models broken, current trust models are also and must be realigned and rebuilt. The only way to do that is to change the emphasis. Shift the focus from infrastructure to the user and it doesn’t matter how complex technology has become, or becomes in the future, the security model remains simple and hence both manageable and relevant.
Moreover, whether the environment is owned by the business, third party, or in the cloud, when access is based on users and application, only a user with cryptographic keys and credentials gains access. It is that simple.
Your trusted advisor is telling you not to worry; you can do encryption on your firewall, switches and routers for less money and achieve the same result.
Turning on encryption in a network device WILL degrade the performance, typically by 50 per cent. The reason lies in the way encryption has been deployed to date.
To address the continued friction between operational goals and security imperatives, organisations need to decouple encryption from the infrastructure completely. The answer is Layer 4 encryption.
Layer 4 encryption is dedicated to providing the level of trust of data in motion and applications moving across the infrastructure, yet avoids any impact on network performance and complexity. Furthermore, Layer 4 operates in ‘stealth’ mode: it is only the data payload that is encrypted – not the entire network data packet.
All of the complex management and maintenance problems created by traditional encryption deployment are removed. The data in motion is secure without adding complexity or compromising the operational performance of the infrastructure.
You’ve been advised that don’t need encryption because your firewalls will keep the hackers out, or if not your Intrusion detection will let you know immediately so you can stop a breach while it’s happening.
Current security thinking must move away from outdated thinking about securing the perimeter, assuming that breaches can be ‘protected’ against, ‘detected’, and ‘reacted’ to. But with the average time to detection being 120 to 150 days, depending on the source, this clearly is a fallacy.
When it comes to data breaches, it is ‘when’ not ‘if’ it happens, so organisations must think about how they can best ‘contain’ a hacker from wreaking havoc on their data.
You prefer complexity over simplicity and are happy to spend the money on complex solutions and highly skilled staff to manage them.
You need to look at indirect costs as well as direct. The more management you have the more you’ll spend.
Thought leadership and innovation are not important. Why should you look at doing something that you do today, but in a better, simpler, more cost-effective, more scalable way?
The hacking community is always trail-blazing ahead. What’s more, the game has changed; it’s no longer about the high profile, kudos-winning breaches. Today’s hacking community is far more focused on the theft of sensitive, customer data that will leave those affected with long-term repercussions.
Cybersecurity must be a process of continual evolution: Just because you feel protected today doesn’t mean you will be tomorrow. Data compromise is something that happens to other businesses, not yours!
That’s what all the brands that have been in the headlines over the past 18 months thought as well.
