“Can I add my work email to my phone?”

Before you say yes, you need to know how the phone will be secured and how company data can be removed if it’s lost or the employee leaves.

You should also decide what staff can access, who provides support, and how personal information will be kept separate from business data.

Read what to decide before staff use personal devices for work

Summary: Allow personal devices only for approved work, through approved apps, and when the device meets your security requirements. Use company-owned devices for administration, sensitive work, or jobs that require large amounts of data to be stored locally. Employees often use personal devices for...

Could someone who didn’t set up your systems understand how they fit together?

A current network diagram should show your internet connection, firewall, switches, wireless access points, servers, important cloud services and how they connect. It should also record key device names and network addresses.

Update it whenever equipment or services change. Store a copy somewhere you can reach during an outage.
The diagram will help when troubleshooting a problem, replacing equipment, planning an upgrade or responding to a security incident.

If your IT documentation exists only in one person’s head, contact us. We can help you document it.

DNS filtering can stop a dangerous website before it opens.

When you click a link, your device uses DNS to find the website. DNS filtering checks the address against known phishing, malware and scam sites. If it finds a match, it blocks the page.

It can protect company computers inside and outside the office, depending on how it is set up.

It will not catch every dangerous site, and legitimate pages can occasionally be blocked. Your IT provider should review the reports, handle exceptions and check that every managed device is covered.

Want to know whether your business already uses DNS filtering? Ask us to check.

An FBI official said the bureau identified a North Korean remote IT worker who had been working for a US government agency.

The agency was not named. The FBI also did not say how the person was hired, how long they worked there or what they could access. North Korean remote workers have used fake identities and people in other countries to receive company laptops on their behalf.

Before hiring someone remotely for a role with access to important systems, verify their identity, previous employment and location. Send company equipment only after those checks are complete.

Hiring remote employees or contractors? We can help you limit their access to the systems and information their role requires.

The investigation shows that North Koreans are able to infiltrate government agencies, as well as private organizations and crypto exchanges.

Don't trust hotel Wi-Fi. It can be compromised even when you've joined the correct network.

Microsoft has found attackers taking control of the systems used for Wi-Fi login pages at hotels and conference venues. Once the login system has been compromised, guests can be redirected to a fake Microsoft 365 sign-in page or shown a fake browser update that installs malware.

The timing makes the request believable. You've just connected, the hotel page opens and it says an update is needed before you can continue. Checking the network name with reception won't help because the hotel's real Wi-Fi is involved.

Use your phone's hotspot for work whenever possible. If you have to use hotel Wi-Fi, never enter your work password into the hotel registration page. And if the page asks you to download an update, certificate or security tool, disconnect. Joining Wi-Fi shouldn't require you to install anything.

If your staff travel with work laptops, send us a message before their next trip. We'll make sure the devices are properly protected.

Who controls the main admin account for your accounting software, CRM and file storage?

Your company should control it. Don’t tie it to one employee’s personal email address or phone number.
➡️ The main account uses a company-owned email address.
➡️ At least two trusted people have admin access.
➡️ Billing and recovery details are current.
➡️ You can still access the service when an employee leaves.

Not sure who owns your critical accounts? Ask us to check them with you.

Sending the same email to a group of customers?

Put their addresses in BCC, not To or CC. Each person will receive the message without seeing everyone else’s email address. It also prevents the whole list from receiving every reply.

For regular newsletters or large lists, use an email marketing platform. It manages unsubscribes and reduces the chance of exposing your customer list by mistake.

Administrator access allows employees to install software and change security settings on their computers.

If an account is compromised, that same access can give malicious software more control.

Most employees can work from a standard account and use a separate administrator account only when necessary.

A short power cut can shut down your router, firewall, switches and local server.

An uninterruptible power supply, or UPS, provides temporary battery power to the equipment connected to it. It can keep your internet equipment and internet-based phones working during a short outage, or give a server time to shut down safely.

UPS batteries wear out. Ask your IT provider which equipment is connected to a UPS and when each battery was last tested or replaced.

If you don’t have an IT provider, or you want a second pair of eyes on your power protection, reach out. We’ll help you identify what needs a UPS, choose the right equipment and make sure the UPS is tested.
