Do I need more memory or more storage?

Have you heard someone say “My computer’s running slow, I need to delete something”?

They’ve probably confused storage with memory.

A PC might have 8 GB of memory and 500 GB of hard disk storage. Both are described in the same units - gigabytes, but notice the very different quantities.

Memory (or RAM) affects how many different things the computer can process at the same time - basically how many apps you can have open at the same time.

Storage (or hard disk space) affects how many documents, photos, music etc you can save.

Unless your hard disk is completely full, deleting things will not speed up your computer. But if you have a lot of apps open, closing some might.

In a business environment it does not make sense to try and sort these things out yourself, you’ll spend time, money and energy on the wrong solutions to your difficulty. Instead, engage telanova as your IT team.

Demonstrate to your clients you have adequate cyber protection

Most people understand how to physically secure their organisation, locks on the doors and windows, burglar alarm, security camera's etc. But most people don't understand cyber security, how do you make sure the protections you have in place are sufficient? How do you demonstrate that to your clients?

Cyber Essentials is a simple but effective, government-backed certification scheme that will reassure you and your customers that you are following best practices and have adequate protections in place. It only costs £300 and also includes cyber insurance.

We’ve done it ourselves, click here and search for telanova for proof. We've also guided several of our customers through the process, getting up to the standard and passing the certification.

If you would like to talk about how we can help your business pass the Cyber Essentials certification please get in touch.

It is time to fill the gaps in your work from home security

At the start of lockdown a customer instructed us to set up an office PC for colleagues to access remotely from home… but in an insecure way. We explained the risks from hackers etc, but they wanted to wing it. Sure enough three weeks later, our monitoring detected hackers trying to hack into the PC, trying thousands of username and passwords.

To mitigate the threat we proposed setting up a private VPN to add an extra layer of security (no, not one of those you use to watch US Netflix, football). We setup their home computers, and showed them how to connect, eliminating the risk.

Lots of organisation cut corners, quite understandably when Covid started. Now is a good time to review home worker security:

  • Secure their logons
    Implement Multi Factor Authentication (MFA or 2FA). A strong password on it’s own isn’t enough. Multi factor involves an extra security step, such as an SMS or app on a phone, or biometric method such as fingerprint or facial recognition.
  • Encrypt their connection
    When users connect to your office, deploy an encrypted VPN connection. This ensures the connection between their computer and your servers is secure and the data transferred cannot be intercepted. When using cloud services make sure they use secure HTTPS connections.
  • Manage their devices
    Deploy Mobile Device Management (MDM). An MDM system will allow you to monitor, manage and secure laptops, smartphones and similar devices. If a device is lost or stolen it can be locked or wiped remotely.
  • Protect their devices
    Have a firewall that is enabled and configured correctly on the device, and use Antimalware Software that is updated and monitored.
  • Secure your business data
    Encrypt hard drives and USB drives with a technology such as Bitlocker, arrange for data to be securely backed up, and have your staff aware that they should only save data in secure locations for compliance with relevant legislation such as GDPR and PCI.

Finding files created by colleagues now furloughed

Our helpdesk received an urgent request from a customer - find a really important spreadsheet. It was created by a colleague who is now on furlough and can’t be contacted. Without it they couldn’t bill their clients! The only thing they could tell us about it was that it probably had “Shoe” in the name...

This client has 30 terabytes of data spread across 5 file servers in 4 locations. They also have a well partitioned folder structure with locked down permissions.

The built in Windows Search is useless for this task as it will only display results for folders you have access to.

We know a clever trick for searching for files: use a utility that reads the Master File Table (MFT) directly, such as WizFile. We found it in less than 30 minutes. It didn't even have “Shoe” in the name in the end.

Your organization deserves a highly skilled competent support team like telanova.

If your servers were overheating would you know in time?

Remember the recent heatwave?

It’s a big problem for customers with on-site servers: the servers need cool air to disperse the heat they are generating. That’s why we continuously monitor server temperatures for customers.

Almost every electronic device generates heat. Servers generate a lot of heat and the harder they have to work the hotter they get. They have fans to expel the heat and draw in cooler air. But there are limits, if the servers are sucking in air that’s too hot, then the server will shutdown (possibly causing data loss).

A typical temp limit for the air going into the server is 42C. However, prolonged operation at high temperatures reduces the life of components, they will break more often, the system will be less reliable. This increases the risk of data loss and system downtime.

Obviously air conditioning is a great option and keeps the ambient temperature low and the systems running smoothly. In addition to this creating space around the servers for air to flow really helps. If a server or cabinet is pushed up against a wall or cluttered with boxes it can really reduce the effectiveness of the cooling. Dust is also the enemy of cooling as it has an insulating effect and reduces airflow.

With targeted monitoring we get an early warning and take action.

In one dramatic case the aircon broke down for a customer with six high power servers in a small server room. Normally their ambient temperature would be 15 degrees even in a heatwave. But now the servers were approaching “meltdown”. The customer had no idea their servers were heating up... except us. We called the customer and advised we would shut down the servers to prevent permanent damage.

Worried that your server is too hot (or want to be alerted when it is)?
