IT3000: Stay Safe Online – Increased Cyber Security Threats

Increased Cyber Security Threats

You may have heard of the security issues many organisations including the NHS have had over the past few days. Microsoft has said that the exploit code used by “WannaCrypt” was designed to work only against unpatched Windows 7 and Windows Server 2008, or even earlier systems such as Windows XP. But lessons should be learnt from this incident.

We want to run through some security basics and hope you can pass on to all your colleagues and friends:

Email:

Don’t open attachments on emails where you don’t recognise the sender. Often the emails will look like they come from “Paypal,” “Ebay” and other known sources. If you are in doubt, delete the email and go to the known website and view the message there.

Don’t take financial instruction from email. We have seen an increase in emails seemingly from a business Director asking for payments to be made to a new supplier account. Have a procedure in place where any new account setup needs a second form of confirmation (even verbal).

Don’t click on suspicious files in any email. If in doubt, call the sender to ensure the email is valid.

If you have accidentally clicked on a suspicious file TURN YOUR COMPUTER OFF don’t run through any setup screens just press the power button for a few seconds. Then call us

Web Browsing:

Make sure you are using a modern browser (Edge or Chrome) and make sure it is up to date.

Ensure you are running anti-virus and this is kept updated.

We would advise any customer still having to run XP that you limit any web browsing and email on these computers.

If you are running Windows XP or Windows Server 2003, Microsoft have released a Security Patch. PLEASE MAKE SURE THIS IS APPLIED.

General Security:

Please make sure all your devices are running anti-virus.

Please make sure you have run Windows update.

Keep your devices clean.

Only install software from trusted sources and don’t leave trial or demo software installed.

If you are a managed support customer of IT3000, we can automatically patch your servers, we just need confirmation of what time we can schedule a restart.

We would recommend:

Windows 10 on your desktop (minimum Windows 8.1).

Windows Server 2016 for you server (Minimum Server 2012 R2).

A Unified Security Firewall device. This adds Intrusion Prevention, Anti-virus and web-filtering on your network border.

Microsoft Office 365 for your Email.

Anti-virus installed on your devices.

Education for you colleagues.

A very good, and proven, backup for critical data.
