Rethinking cellular security in the post-COVID workplace

 

In the global globe of enterprise cellular security, horrible situations force protection corner-cutting to preserve the business sometimes. And COVID-19 forcing companies to empty workplace buildings and shift everything (and everyone) to remote places and the cloud in March 2020 may be the classic example. What resulted in the security shortcuts had not been the abrupt modification to home based just, but the proven fact that companies had to help make the transition in just a few days typically.

Increase that increased issues with IoT security – specifically as IoT devices in house environments accessed global techniques via VPNs, occasionally spreading malware through the pipeline – and chaos is had by you. A recently available Verizon mobile security review put it bluntly: “Nearly 1 / 2 of respondents admitted that their business had knowingly slice corners on mobile gadget security. That’s a rise from our 2020 survey once the figure was 46%. The proportion rises to two-thirds [67%] inside our IoT sample. And of these staying, 38% (27% IoT) arrived under pressure to take action. Another way of considering that is that 68% emerged under pressure to lower corners and 72% of these succumbed.”

A fast note to place those amounts in context: It is a survey. How many safety executives understood they had trim corners, but had been scared to admit it on paper. Security advantages know much better than anyone how data may leak easily. So  the truth is likely worse compared to the Verizon information suggest even.

There exists a more frightening issue: when i sit here some 13 months following this happened, way too many holes have however to be plugged much. CISOs also it teams have already been so insanely occupied (and understaffed) just attempting to keep functions up and to not really create any new protection holes, they haven’t had the chance to repair old vulnerabilities.

Which means that C-suite leaders – the CFOs, CEOs and coos – have to budget and insist upon fixes happening.

In the meantime, here are a few easy fixes to start to lessen your COVID-related risks:

Dual LANs in remote control sites , specifically home offices

 

This is easy to do, relatively inexpensive (worst case scenario, you’ll have to buy one additional router for every site) and can sharply reduce your contact with the demons from the consumer-grade devices in the house, including kid’s games, home IoT devices, a laptop/cell phone that visits high-risk websites and freely downloads God has learned what also.

The policy rule is easy. As now, you should create a corporate-just LAN and all business devices must make use of that LAN and just that LAN. Which means a laptop useful for work purposes. For a separate phone, that, as well. (See suggestion No. 2.)

Revisit BYOD

 

Please i want to stress: The idea here’s to totally and thoroughly evaluation BYOD policies, not abandon it necessarily. There are numerous variables to pursue that as well. The key details: Determine what your enterprise’s plans for remote control work will undoubtedly be in late 2021 and most of 2022.

When most enterprises moved to BYOD (not absolutely all have, needless to say), they did so under starkly different circumstances. There’s been a statistical risk analysis to BYOD always, namely something similar to: “Let’s take action, but due to the fact 90% of enterprise communications are not done on personal mobile, there exists a limit to just how much trouble we are able to get ourselves in.” This is actually the same logic that permitted suboptimal security in home offices before COVID-19. Considering that the common enterprise had 10% or fewer of its employees working at home, some considered it unnecessary/not-cost-effective to invest a complete bundle to secure them.

But today, with a lot more activity happening at remote sites and via cellular devices, BYOD must be reconsidered.

Heading back to my first suggestion (dual-LAN), there’s a limit to risk-reduction if the employee/contractor gets in the smartphone that’s also accessing high-risk sites and includes suspect apps. To obtain the most reap the benefits of an enterprise-only LAN, you will need to obtain strict and, this means re-thinking-through your BYOD policy.

Various other considerations: the partition approach has only been partially successful. One argument for separating personal and corporate data and apps on a phone is that when corporate data is reported missing or stolen, a restricted remote wipe can protect enterprise data while leaving personal data untouched.

But that’s delivered mixed results, which has managed to get people hesitant to remote wipe. The longer remote wipe isn’t executed (perhaps to allow employee/contractor more time to discover the device), the more pointless it becomes. IT and security pros need to assume a lost phone is in the possession of a negative guy.

A corporate-owned device, on the other hand, would presumably be simpler to wipe since there is no danger that personal info will be lost.

Another consideration: smartphones in 2021 are leveraging more and better backup options. Which means a remote wipe won’t secure all enterprise data even. Let’s say an contractor or employee quits, is let go or is fired. Those backups are from the selection of IT invariably. In a well-managed corporate device, more data is controlled.

Also, remote wipe today isn’t what it was previously. It involved literally wiping all data off a phone once. Though it still technically does that, more often than not it’s less a wipe when compared to a disconnect from enterprise assets (more often than not cloud-based). That still works on a BYOD device even.

Revisit mobile device managment

 

Unlike BYOD, the theory here isn’t to revisit whether you need to use Mobile Device Management (MDM) or not – it’s about deciding which to select and whether it’s time and energy to upgrade or revisit your configuration decisions. With mobile a more prevalent data-control mechanism now, re-thinking MDM in 2021 could yield different decisions.

In short, today you may be in a position to cost-justify a higher-level MDM solution. Crunch the true numbers, have the meetings, today and discover review product options.

Doug Barbin, a principal at the Schellmen & Co. consulting firm (and a really insightful analyst), argues that, “MDM technology advanced anymore so that it ’s not all-or-nothing. Everyone rushed into availability, nevertheless, you don’t need all this access.” Barbin stresses that IT and security admins focused less on the least-privilege goal than they ought to have. “They gave users usage of everything they needed and started ratcheting in the past.”

That’s a textbook exemplory case of the contrary of least-privilege.

Coping with user pushback

 

The largest single problem with pandemic-related enterprise security efforts today may be the popular user (and frequently manager) rationalization: “I’m just attempting to do my job.”

That’s always code for nearly, “Your security requirements are taking enough time and effort too. I’m attempting to now do an end-run around them actively. ” This started right with COVID-19 away, when VPNs (seeing massive increases in usage) slowed to a crawl and users desperately tried to sidestep them to obtain their work done. Line-of-business  managers either applauded those efforts or aggressively ignored them often.

That has been proof that corporate security also it pros hadn’t done a sufficiently good job of selling the advantages of sticking with security rules. That should be re-evaluated as well.

Companies have discovered many lessons before 13 months roughly, the right, some bad. With regards to security, now’s enough time to re-think how things have already been handled before and what they ought to look like in the years ahead.
