Securely Working from Home
Amidst the coronavirus pandemic, governments are moving into the “delay” phase of their strategy to fight the virus. This includes social distancing techniques including closing some businesses and asking people to work from home. Elsewhere, people are having to or opting to work remotely to self-isolate or to simply help slow the spread of the virus.
The internet era and progress in technology has made it trivially simple for many of us to carry out our regular duties from the comfort of our home office. That said, this luxury comes with its downsides, mainly by way of online security threats. Not only can remote workers have their own privacy put at risk, working from home could result in breaching company security too.
As working from home becomes the ‘new normal’, let’s look at some tips to help you stay safe online so you can do your job with peace of mind.
Online threats to remote workers
Before delving into the tips, let’s take a look at a few of the online threats that remote workers should be aware of.
Unsecured wifi networks: Most workers will be working out their home where they can secure their wifi. But some may have to use unsecured public wifi networks which are prime spots for malicious parties to spy on internet traffic and collect confidential information.
Using personal devices and networks: Many workers will be forced to use personal devices and home networks for work tasks. These will often lack the tools built in to business networks such as strong antivirus software, customized firewalls, and automatic online backup tools. This increases the risk of malware finding its way onto devices and both personal and work-related information being leaked.
Scams targeting remote workers: We’ll likely see an increase in malicious campaigns targeting remote workers. What’s more, with many employees lacking remote work opportunities, we’ll no doubt see an increase in the prevalence of work-from-home scams.
Thankfully, armed with the right knowledge and tools, you can stave off many of these threats and continue getting your work done.
Cybersecurity tips for staff working remotely
Note that before you take your own measures to protect your online security, you should check in with the Infosec team. In light of the COVID-19 crisis, everyone is putting together work-from-home plans. Your manager will be able to provide you with specific directions on how to handle certain aspects of cybersecurity and perhaps provide access to some of the tools you need.
Thankfully, even if your manager doesn’t offer solutions to every home-based working issue, there are some simple steps you can take to protect yourself while working from home:
- Use strong passwords – always
- Set up / use two-factor authentication
- Use the approved VPN
- Set up firewalls on your home internet
- Use antivirus software
- Secure your home router
- Install updates regularly
- Back up your data
- Beware of unapproved remote desktop tools
- Look out for phishing emails and sites
- Watch out for work-from-home scams
- Use encrypted communications
- Lock your device
Let’s look at each of these in detail:
1. Use strong passwords
It’s as important as ever to ensure that all accounts are protected with strong passwords. Unfortunately, many people still use the same password across multiple accounts. This means that all it takes is one compromised password for a criminal to take over all of your accounts. They take leaked usernames and passwords and attempt to log into other online accounts, a tactic called credential stuffing.
Passwords should be unique for every account and should comprise a long string of upper and lower case letters, numbers, and special characters. Clearly, it’s difficult to remember all these passwords, which is why password managers are such popular tools these days.
LastPass, KeePass and Thycotic Secret Server
A password manager will create, remember, and autofill passwords for you. LastPass and KeePass are two of our favorites for home use. Thycotic Secret Server is the Enterprise Alternative for password vaulting.
2. Set up and use two-factor authentication
Having a strong password often isn’t enough, for example, if your credentials are leaked in a data breach. Two -factor authentication (2FA) and two-step verification (2SV) involve an additional step to add an extra layer of protection to your accounts.
The extra step could be an email or text message confirmation, a biometric method such as facial recognition or a fingerprint scan, or something physical, such as a USB fob or Yubikey.
3. Use a VPN
Many people are familiar with using a Virtual Private Network (VPN) to bypass geographic restrictions on streaming sites and other location-specific content. Indeed, since a VPN tunnels your traffic through a server in location of your choice, it’s ideal for location spoofing.
But a VPN has another important role, and that’s improving your online privacy. A VPN encrypts all of your internet traffic, so that it is unreadable to anyone who intercepts it. This keeps it away from the prying eyes of any snoopers, including your Internet Service Provider (ISP), government agencies, or hackers.
Note that using a VPN can slow down internet speeds. If you need to perform high-bandwidth tasks such as holding video conference calls, you need a VPN known for its speed and reliability. Always use the corporate VPN when working on company assets.
4. Set up firewalls on your Home Internet
Firewalls act as a line defense to prevent threats entering your system, They create a barrier between your device and the internet by closing ports to communication. This can help prevent malicious programs entering and can stop data leaking from your device.
Your device’s operating system will typically have a built-in firewall. In addition hardware firewalls are built in to many routers. Just make sure that yours are enabled.
If you don’t have a built-in firewall or are looking for some added protection, there are plenty of third party firewalls available.
5. Use antivirus software
Although a firewall can help, it’s inevitable that threats can get through. A good antivirus software can act as the next line of defense by detecting and blocking known malware.
Even if malware does manage to find its way onto your device, an antivirus may be able to detect and in some cases remove it.
Trend Micro, Norton antivirus software.
Trend Micro, Norton, McAfee, and Bitdefender are some recommended options if you don’t already have antivirus software.
6. Secure your home router
Do you know if you changed your router password when it was first installed? Many people didn’t, leaving their home network vulnerable. It’s important to take simple steps to protect your home network to prevent malicious parties having access to connected devices.
Changing your router password is a good first step, but there are other actions you can take. For example, you should make sure firmware updates are installed so that security vulnerabilities can be patched. The encryption should be set to WPA2 or WPA3. Restrict inbound and outbound traffic, use the highest level of encryption available, and switch off WPS. To learn more about securing your home router you can check out our dedicated guide.
7. Install updates regularly
Updates to device software and other applications can be a source of annoyance. But they really are important. Corporate systems are managed externally. But your home workstations rely on your diligence! Updates often include patches for security vulnerabilities that have been uncovered since the last iteration of the software was released.
In many cases, you can set updates to run automatically, often while you’re sleeping, so you don’t have to worry about downtime.
8. Back up your data
Data can be lost in a number of ways, including human error, physical damage to hardware, or a cyberattack. Ransomware and other types of malware can wipe entire systems without you having a chance to spot it
Clearly, there are plenty of reasons to keep your data backed up. While hardware backups are still an option, one of the most convenient and cost-effective ways to store your data is OneDrive. Cloud backup services come with a wealth of options enabling you to customize your backup schedule and storage options.
9. Beware of unapproved remote desktop tools
We all access work networks via a range of Remote Access tools. While this can be secure, a 2019 Check Point study found security problems with some of the most popular RDP tools for Linux and Windows. Always used the approved VPN and Remote Access methods.
10. Look out for phishing emails and sites
Phishing emails, as well as voicemails (vishing) and text messages (smishing) are used by cybercriminals to “phish” for information. This information is usually used in further schemes such as spear phishing campaigns (targeted phishing attacks), credit card fraud, and account takeover fraud.
With the rise in the number of people working from home due to the coronavirus outbreak, no doubt there will be plenty of cybercriminals looking to cash in on the trend. It’s highly likely that phishing emails will target remote workers in a bid to steal their personal information or gain access to company accounts.
To spot a phishing email, check the sender’s email address for spelling errors and look for poor grammar in the subject line and email body. Hover over links to see the URL and don’t click links or attachments unless you trust the sender 100 percent. If in any doubt, contact the alleged sender using a phone number or email address that you find somewhere other than in the suspicious email.
If you do click a link and end up on a legitimate-looking site, be sure to check its credibility before entering any information. Common signs of a phishing site include lack of an HTTPS padlock symbol (although phishing sites increasingly have valid certificates), misspelled domain names, poor spelling and grammar, lack of an “about” page, and missing contact information.
11. Watch out for work-from-home scams
As well as targeted phishing attacks, we’re likely to see an increase in work-from-home scams and other schemes that typically target gig economy workers. Many of these request personal information or upfront payments before you can begin work. By the time you realise it’s a scam, the fraudster has ceased contact and stolen your money or taken over accounts.
If you’re looking for freelance work, use reputable sites that offer protection to both clients and freelancers such as Upwork and Freelancer. Never share personal information with a client that you haven’t thoroughly researched. And don’t work with anyone who requests an upfront fee.
Also be on the lookout for pyramid and multi-level-marketing (MLM) scams as these are often well-disguised as legitimate and attractive work-from-home opportunities.
12. Use encrypted communications
Of course, there are times when you need to communicate with fellow workers, and it’s common for those emails to include sensitive information. If your company doesn’t already provide you with secure methods of communication, you may have to come up with your own options.
Thankfully, many mainstream messaging services such as Signal, WhatsApp, And Telegram come with end-to-end encryption as default or as an option.
13. Lock your device
If you do have to work in a public space, or if you live with people who you can’t share work information with, then it’s important to keep your device secure. Password-locking your device will usually encrypt its contents until someone enters the password.
If you’re looking for more protection, you can use an additional full disk encryption tool such as BitLocker.
If you need to physically lock your device, for example, at a library or hospital, a Kensington lock is a great option.
