The global pandemic caused by the novel coronavirus is changing work environments to an unprecedented degree. More employees than ever are being asked to work remotely from home. Along with the new work practices comes a variety of security challenges.

Without the proper precautions, working from home could become a cybersecurity nightmare, says Purdue University professor Marcus Rogers. “Criminals will use the crisis to scam people for money, account information and more,” he says. “With more people working from home, people need to make sure they are practicing good cybersecurity hygiene, just like they would at work. There is also a big risk that infrastructures will become overwhelmed, resulting in communication outages, both internet and cell.”

Covid-19 concerns 

Concerns about the coronavirus have increased the business world’s dependence on teleworking. According to Cisco Systems, WebEx meeting traffic connecting Chinese users to global workplaces has increased by a factor of 22 since the outbreak began. Traffic in other countries is up 400% or more, and specialist video conferencing businesses have seen a near doubling in share value (as the rest of the stock market shrinks).

Basic email security has remained unchanged for 30 years

Email is a core element of business communications, yet basic email security has remained unchanged for 30 years. Many smaller businesses are likely to still be using outdated Simple Mail Transfer Protocol (SMTP) when sending and receiving email. “The default state of all email services is unencrypted, unsecure and open to attack, putting crucial information at risk,” says Paul Holland, CEO of secure email systems provider Beyond Encryption.

“With remote working a likely outcome for many of us in the coming weeks, the security and reliability of our electronic communication will be a high priority,” says Holland. The company’s Mailock system allows employees to work from any device at home or in the office without concerns about data compromise or cybersecurity issues.

Acting quickly and effectively 

As the virus spreads, businesses and organisations will need to act quickly to establish relevant communication with their employees, partners and customers surrounding key coronavirus messages, says Heinan Landa, CEO and Founder of IT services firm Optimal Networks. Employers should also enact proper security training to make sure everyone is up to speed with what’s happening and can report any suspicious online activity.

Reviewing and updating telework policies to allow people to work from home will also provide flexibility for medical care for employees and their families as needed.

Scammers, phishing, and fraud 

An additional factor in the confusing environment created by the coronavirus is growth in phishing emails and creation of domains for fraud. Phishing is an attempt to fraudulently obtain sensitive information such as passwords or credit card information by disguising oneself as a trusted entity. Landa says homebound workers should understand that phishing can come from a text, a phone call, or an email. “Be wary of any form of communication that requires you to click on a link, download an attachment, or provide any kind of personal information,” says Landa.

Email scammers often try to elicit a sense of fear and urgency in their victims – emotions that are more common in the climate of a global pandemic. Attackers may disseminate malicious links and PDFs that claim to contain information on how to protect oneself from the spread of the disease, says Landa. 

Ron Culler, Senior Director of Technology and Solutions at ADT Cybersecurity, offers some cyber and home security tips for remote workers and their employers:

  • When working from home, workers should treat their home security just as they would if working from the office. This includes arming their home security system and leveraging smart home devices such as outdoor and doorbell cameras and motion detectors. More than 88% of burglaries happen in residential areas.
  • When possible, it’s best to use work laptops instead of personal equipment, which may not have adequate antivirus software and monitoring systems in place. Workers should adhere to corporate-approved protocols, hardware and software, from firewalls to VPNs.
  • Keep data on corporate systems and channels, whether it’s over email or in the cloud. The cyber-protections that employees depended on in the office might not carry over to an at-home work environment.
  • Schedule more video conferences to keep communication flowing in a controlled, private environment.
  • Avoid public WiFi networks, which are not secure and run the risk of remote eavesdropping and hacking by third parties.

In addition to work-from-home strategies, companies should consider ways to ensure business cyber-resilience and continuity, says Tim Rawlins, Director and Senior Adviser for risk mitigation firm NCC Group. “Given that cyber-resilience always relies on people, process and technology, you really need to consider these three elements,” he says. “And your plan will need to be adaptable as the situation can change very quickly.”

Employees and their employers

Self-isolation and enforced quarantine can impact both office staff and business travelers

Self-isolation and enforced quarantine can impact both office staff and business travelers, and the situation can change rapidly as the virus spreads, says Rawlins.

Employees should be cautious about being overseen or overheard outside of work environments when working on sensitive matters. The physical security of a laptop or other equipment is paramount. “It’s also important to look at how material is going to be backed up if it’s not connected to the office network while working offline,” says Rawlins.

It’s also a good time to test the internal contact plan or “call tree” to ensure messages get through to everyone at the right time, he adds.

Managing security during unprecedented times of home working
Managing security during unprecedented times of home working

Companies are following government guidance and getting as many people as possible working from home. Some companies will have resisted home working in the past, but I’m certain that the sceptics will find that people can be productive with the right tools no matter where they are. A temporary solution will become permanent. But getting it right means managing risk. Access is king In a typical office with an on-premise data centre, the IT department has complete control over network access, internal networks, data, and applications. The remote worker, on the other hand, is mobile. He or she can work from anywhere using a VPN. Until just recently this will have been from somewhere like a local coffee shop, possibly using a wireless network to access the company network and essential applications. CV-19 means that huge numbers of people are getting access to the same desktop and files, and collaborative communication toolsBut as we know, CV-19 means that huge numbers of people are getting access to the same desktop and files, applications and collaborative communication tools that they do on a regular basis from the office or on the train. Indeed, the new generation of video conferencing technologies come very close to providing an “almost there” feeling. Hackers lie in wait Hackers are waiting for a wrong move amongst the panic, and they will look for ways to compromise critical servers. Less than a month ago, we emerged from a period of chaos. For months hackers had been exploiting a vulnerability in VPN products from Pulse Secure, Fortinet, Palo Alto Networks, and Citrix. Patches were provided by vendors, and either companies applied the patch or withdrew remote access. As a result, the problem of attacks died back.  But as companies race to get people working from home, they must ensure special care is taken to ensure the patches are done before switching VPNs on. That’s because remote desktop protocol (RDP) has been for the most part of 2019, and continues to be, the most important attack vector for ransomware. Managing a ransomware attack on top of everything else would certainly give you sleepless nights. As companies race to get people working from home, they must ensure special care is taken to ensure the patches are done before switching VPNs on Hackers are waiting for a wrong move amongst the panic, and they will look for ways to compromise critical serversExposing new services makes them also susceptible to denial of service attacks. Such attacks create large volumes of fake traffic to saturate the available capacity of the internet connection. They can also be used to attack the intricacies of the VPN protocol. A flow as little as 1Mbps can perturbate the VPN service and knock it offline. CIOs, therefore, need to acknowledge that introducing or extending home working broadens the attack surface. So now more than ever it’s vital to adapt risk models. You can’t roll out new services with an emphasis on access and usability and not consider security. You simply won’t survive otherwise. Social engineering Aside from securing VPNs, what else should CIO and CTOs be doing to ensure security? The first thing to do is to look at employee behaviour, starting with passwords. It’s highly recommended that strong password hygiene or some form of multi-factor authentication (MFA) is imposed. Best practice would be to get all employees to reset their passwords as they connect remotely and force them to choose a new password that complies with strong password complexity guidelines.  As we know, people have a habit of reusing their passwords for one or more online services – services that might have fallen victim to a breach. Hackers will happily It’s highly recommended that strong password hygiene or some form of multi-factor authentication (MFA) is imposedleverage these breaches because it is such easy and rich pickings. Secondly, the inherent fear of the virus makes for perfect conditions for hackers. Sadly, a lot of phishing campaigns are already luring people in with the promise of important or breaking information on COVID-19. In the UK alone, coronavirus scams cost victims over £800,000 in February 2020. A staggering number that can only go up. That’s why CIOs need to remind everyone in the company of the risks of clickbait and comment spamming - the most popular and obvious bot techniques for infiltrating a network. Notorious hacking attempts And as any security specialist will tell you, some people have no ethics and will exploit the horrendous repercussions of CV-19. In January we saw just how unscrupulous hackers are when they started leveraging public fear of the virus to spread the notorious Emotet malware. Emotet, first detected in 2014, is a banking trojan that primarily spreads through ‘malspam’ and attempts to sneak into computers to steal sensitive and private information. In addition, in early February the Maze ransomware crippled more than 230 workstations of the New Jersey Medical Diagnostics Lab and when they refused to pay, the vicious attackers leaked 9.5GB or research data in an attempt to force negotiations. And in March, an elite hacking group tried to breach the World Health Organization (WHO). It was just one of the many attempts on WHO and healthcare organisations in general since the pandemic broke. We’ll see lots more opportunist attacks like this in the coming months.   More speed less haste In March, an elite hacking group tried to breach the World Health Organization (WHO). It was just one of the many attempts on WHOFinally, we also have bots to contend with. We’ve yet to see reports of fake news content generated by machines, but we know there’s a high probability it will happen. Spambots are already creating pharmaceutical spam campaigns thriving on the buying behaviour of people in times of fear from infection. Using comment spamming – where comments are tactically placed in the comments following an update or news story - the bots take advantage of the popularity of the Google search term ‘Coronavirus’ to increase the visibility and ranking of sites and products in search results. There is clearly much for CIOs to think about, but it is possible to secure a network by applying some well thought through tactics. I believe it comes down to having a ‘more speed, less haste’ approach to rolling out, scaling up and integrating technologies for home working, but above all, it should be mixed with an employee education programme. As in reality, great technology and a coherent security strategy will never work if it is undermined by the poor practices of employees.

How does audio enhance security system performance?
How does audio enhance security system performance?

Video is widely embraced as an essential element of physical security systems. However, surveillance footage is often recorded without sound, even though many cameras are capable of capturing audio as well as video. Beyond the capabilities of cameras, there is a range of other audio products on the market that can improve system performance and/or expand capabilities (e.g., gunshot detection.) We asked this week’s Expert Panel Roundtable: How does audio enhance the performance of security and/or video systems? 

How have standards changed the security market?
How have standards changed the security market?

A standard is a document that establishes uniform engineering or technical criteria, methods, processes, and/or practices. Standards surround every aspect of our business. For example, the physical security marketplace is impacted by industry standards, national and international standards, quality standards, building codes and even environmental standards, to name just a few.
