Lineal’s Ian awarded Certified DrayTek Network Admin

Lineal’s Ian Meredith has been awarded DrayTek Certified Network Admin Certificate, adding an additional qualification to Lineal’s networking experience.

DrayTek’s ‘Dray School’ requires network engineers to pass a series of advanced network and security configuration tests using DrayTek devices, routers and access points, including best practice for firewall settings, fault-finding and other detailed network tasks.

DrayTek’s business-grade Router range have won praise from across the IT Support sector recent years, with the provider winning a PC PRO Technology Excellence Award for five successive years (2014-18). DrayTek router models have proved highly popular with businesses, with intelligent features such as 4G fail-over increasingly in demand for business continuity requirements.

As a part of the 2-day examination procedure, each engineer’s router is attached to a testing network which judges whether the engineer has managed the device correctly, and automatically passes or fails based on a series of security checks.

Well done Ian!

WPA3 Wi-Fi Introduced

The Wi-Fi Alliance has formally announced the introduction of the WPA3 security protocol, the next generation of wireless security to protect routers and networks.

The new security standard follows hot on the heels of last year’s breach of the existing WPA2 standard, which has been in use since 2004.

WPA3, released in both ‘personal’ and ‘enterprise’ with extra protections, is expected to fix a number of deficiencies in the older WiFi protocol, including:

  • Captured encrypted data cannot be decrypted by a later breach of the password – in order to access data, a hacker must have both the password and data at point of transmission.
  • Encryption of data will be individualised, such that snooping on other devices across less secure Wi-Fi networks will be made more difficult.
  • Extra protections against password brute-forcing and ‘dictionary’ style attacks, dramatically increasingly the time cost of bulk guessing a password successfully.
  • Smart devices with no screen, including many Internet-of-things (IoT) technologies, will be administered via a smartphone screen during Wi-Fi setup.

To most end-users, the experience of entering a Wi-Fi key will feel virtually identical. WPA3 isn’t expected to actually be implemented until 2019, and is predicted to gradually replace the existing WPA2 standard on all Wi-Fi certified devices. WPA2 will continue to function, but will be steadily phased out.

Nevertheless, expect to see major manufacturers rushing to ensure their own products are stamped with the very latest security ‘WPA3 Ready’ branding.

Technology firms rush to fix WPA2 KRACK

Technology firms are urgently issuing fixes for the WPA2 KRACK (Key Reinstallation Attack) thought to compromise the WPA2 encryption used in most WiFi routers and other wirelessly enabled devices.

The exploit, discovered and published by Mathy Vanhoef, a Belgian security expert for Imec-Distrinet, Ku Leuven, has caused serious alarm amongst cybersecurity professionals due to the widespread use of WPA2 across millions of items of networked hardware around the World.

Vanhoef’s website, detailing how the the WPA2 KRACK works, demonstrates on video how an unfortunate Android smartphone can be tricked into re-installing an all-zero encryption key, which makes de-crypting data transmitted from the device possible. 

Security guidance remains to continue using WPA2 (rather than reverting to an older encryption standard) and to install the latest WPA2 KRACK security updates from manufacturers as soon as they are available.

A number of key technology vendors were notified in August, giving them some time to prepare. Microsoft are reported to have adjusted “how Windows verifies windows group key handshakes” to fix the issue. Apple and Android are yet to specify exactly when patches will be available, although both are understood to be working on a secure fix to be made available in coming weeks. The more responsive hardware developers, including Cisco and Ubiquiti, yesterday began issuing guidance and new firmware for their wireless equipment.

The Wi-Fi Alliance, the international organisation dedicated to developing Wi-Fi technology, have essentially argued that there is no need to panic. There is no evidence of the extremely serious hack being deployed outside test conditions (yet) – although it’s probably only a matter of time before someone attempts to do so. Because Wi-Fi relies on physical range, it’s likely this could target public Wi-Fi and other easily accessible networks. For this reason, users are (as always) reminded not to use public networks for sensitive tasks, such as online banking.

It’s clear from the increased publicity surrounding the discovery that major vendors of network equipment will be under pressure to issue the required WPA2 KRACK security patches.

However, the underlying vulnerability also threatens a wide range of wirelessly connected internet-of-things (IOT) devices – including everything from CCTV to smart-fridges – such that it’s unclear just how widespread this latest security flaw will actually prove.

Network overhaul: how Lineal rescued a company from a cabling nightmare

network overhaul

Lineal recently rescued a London-based business from its own private cabling nightmare, with a complete network overhaul.

In a 48-hour marathon rebuild, network engineers from Lineal replaced dozens of faulty cables, analysed every area of the network, adding new switches and other network equipment.

The picture above shows just one of several cabinets, before (left) and after (right) Lineal’s rebuild. The equipment had previously been patched and re-patched over ten years without clear planning, resulting in slower internet access and overheating rooms.

Network engineer Martyn Kay explained: “This company rightly realised that they had to address the problem rather than ignore it – and fortunately we were able to overhaul the entire system.”

The team quickly discovered other unexpected problems, including mystery fibre-optic cables that led nowhere, stray power cables, long-dead switches and improvised cabling ‘borrowing’ internet access from neighbouring departments.

Lineal reconnected every cabinet, replaced every cable with new lines, standardised the colour scheme for data and phones, and added reliable backup switches to improve network resilience and business continuity.

How Lineal provided Free Wifi to Barnstaple Town Centre

 

Over Christmas 2015/16, Lineal launched a technical trial to provide free, public-access Wifi across Barnstaple Town Centre.

The pilot scheme, which took place during the busiest shopping period of the year, saw our team solve a number of technical challenges: scoping sites for Wifi access points, installing suitable hardware and managing network connectivity for shoppers and visitors to the town.

With generous support from Barnstaple Town Centre Management (BTCM), North Devon Council and M&E Alarms, we delivered a free wifi network connected to by more than 400 people each day at peak usage.

To build the network itself, we used Cisco Meraki MR-66 ruggedised outdoor routers, fixing a ‘mesh’ grid of interconnected access points high on selected buildings owned by local businesses who agreed to take part. Visitors to the town could connect from any smartphone or other wirelessely enabled device, via a special ‘splash’ page.

Managing Director of Lineal, Mike Matthews, explained: “We wanted to attempt an ambitious project which would benefit our local area. Wider connectivity opens up new ways for people to find out information about upcoming events, for local businesses to advertise, and for visitors to our town to share their enjoyment of Barnstaple with friends and family over social media. There are many possibilities.”

connectivity trial

Throughout the trial period each access point also collected anonymised location data in real-time. With as many as 20,000 wirelessly enabled devices moving within Barnstaple town centre during a 24 hour period, the free Wifi Project was also successfully used to measure footfall patterns in public places, which could one day be used to help local authorities plan for busy periods.

Although the pilot project has now ended, team members from Lineal presented the initial findings to the Barnstaple Town Centre Management, North Devon Council and Devon County Council in February 2016, with a view to launching the network as a more permanent asset for the town in the near future.

Why your AirDrop isn’t working (and how to fix it)

Airdrop

AirDrop must be prompted to recognise older Apple devices

Apple’s AirDrop tool has been a much praised addition to Apple’s software lineup – allowing Mac users to wirelessly transfer files from one Apple device to another in close proximity.

However users often report that their new Mac is unable to ‘see’ adjacent Mac devices, preventing them from using AirDrop.

The solution is surprisingly simple: look to the bottom of the AirDrop window on the newest manufactured device, where a small link reads “Don’t see who you’re looking for?” clicking this opens a new option “Search for an older Mac”, which widens the search to older devices running OS X or iOS.

There’s been no explanation from Apple as to why Airdrop is set up in this way, but enabling ‘Search for an older Mac’ allows a 2015 Macbook to find a previously invisible 2011 Macbook with ease, allowing you to begin transferring files.

Happy AirDropping!

Bloxx announces discontinuation of products

Bloxx to become part of Akamai Technologies

Web filtering provider Bloxx have announced that they will be ceasing support for their products and services, following a shock email from the company’s Chief Executive.

The move comes as part of a cash deal takeover bid by cloud services firm Akamai Technologies, announced on 2nd November 2015, and will see an end to the sale of all Bloxx products.

Bloxx has a good reputation in the UK and beyond for delivering a strong feature set in their appliances that are used to filter online content delivered in sensitive environments. Their products are commonly implemented by educators, healthcare providers, local authorities and businesses.

Although existing contracts will be honoured, those who have invested in physical Bloxx hardware may well find the lifespans are now limited, with little indication of whether Akamai will offer suitable replacements.

Bloxx’s impressive record has drawn the attention of national media before, with the Edinburgh based-company receiving hate mail from teenagers unable to access restricted websites on school computers even with a range of proxies.

With online security stories dominating the news in recent weeks, wider awareness of the need for web, social media and email monitoring is likely to only increase demand for such products. It remains to be seen whether interested parties will consider a cloud-based offering from Akamai to be sufficient, especially when it comes to security and bandwidth management.
