Dirty secret of network traffic

Published

on

Sophos recently announced the findings of its global survey, The Dirty Secrets of Network Firewalls, which revealed that IT managers cannot identify 45 percent of their organisation’s network traffic.

In fact, nearly one-in-four cannot identify 70 percent of their network traffic. The lack of visibility creates significant security challenges for today’s businesses and impacts effective network management. The survey polled more than 2,700 IT decision makers from mid-sized businesses in 10 countries including the US, Canada, Mexico, France, Germany, UK, Australia, Japan, India, and South Africa.

Considering the debilitating impact cyber-attacks can have on a business, it’s unsurprising that 84 percent of respondents agree that a lack of application visibility is a serious security concern. Without the ability to identify what’s running on their network, IT managers are blind to ransomware, unknown malware, data breaches and other advanced threats, as well as potentially malicious applications and rogue users. Network firewalls with signature-based detection are unable to provide adequate visibility into application traffic due to a variety of factors such as the increasing use of encryption, browser emulation, and advanced evasion techniques.

“If you can’t see everything on your network, you can’t ever be confident that your organisation is protected from threats. IT professionals have been ‘flying blind’ for too long and cybercriminals take advantage of this,” said Dan Schiappa, senior vice president and general manager of products at Sophos. “With governments worldwide introducing stiffer penalties for data breach and loss, knowing who and what is on your network is becoming increasingly important. This dirty secret can’t be ignored any longer.”

On average, organisations spend seven working days remediating 16 infected machines per month. Smaller organisations (100-1,000 users) spend on average five working days remediating 13 machines, while larger organisations (1,001-5,000 users) spend on average 10 working days remediating 20 machines per month, according to the survey.

“A single network breach often leads to the compromise of multiple computers, so the faster you can stop the infection from spreading the more you limit the damage and time needed to clean it up,” said Schiappa. “Companies are looking for the kind of next-generation, integrated network and endpoint protection that can stop advanced threats and prevent an isolated incident from turning into a widespread outbreak. Sophisticated exploits such as MimiKatz and EternalBlue reminded everyone that network protection is critical to endpoint security and vice versa. Only direct intelligence sharing between these two can reveal the true nature of who and what is operating on your network.”

IT managers are very aware that firewalls need an upgrade in protection. In fact, the survey revealed that 79 percent of IT managers polled want better protection from their current firewall. 99 percent want firewall technology that can automatically isolate infected computers, and 97 percent want endpoint and firewall protection from the same vendor which allows for direct sharing of security status information.

Security is Not the Only Risk to Businesses

Following security risks, lost productivity was cited as a concern for 52 percent of respondents when it comes to a lack of network visibility. Business productivity can be negatively impacted if IT is unable to prioritise bandwidth for critical applications.

For industries that rely on custom software to meet specific business needs, an inability to prioritise these mission critical applications over less important traffic could be costly. 50 percent of IT professionals who had invested in custom applications admitted that their firewall could not identify the traffic and therefore were unable to maximise their return on investment. Lack of visibility also creates a blind spot for the potential transfer of illegal or inappropriate content on corporate networks, making companies vulnerable to litigation and compliance issues.

“Organisations need a firewall that protects their investment in business-critical and custom applications by allowing employees to have prioritized access to the applications they need,” said Schiappa. “Increasing network visibility requires a radically different approach. By enabling the firewall to receive information directly from the endpoint security, it can now positively identify all applications – even obscure or custom applications.”

The Dirty Secrets of Network Firewalls survey was conducted by Vanson Bourne, an independent specialist in market research, in October and November 2017. This survey interviewed 2,700 IT decision makers in 10 countries and across five continents, including the US, Canada, Mexico, France, Germany, UK, Australia, Japan, India, and South Africa. All respondents were from organisations of between 100 and 5,000 users.

Sophos can deliver higher levels of network visibility with the XG Firewall and Sophos Endpoint Protection or Intercept X. For information about Sophos XG Firewall, please visit: https://www.sophos.com/en-us/products/next-gen-firewall.aspx

Password managers don’t protect you from hackers

Using a password manager to protect yourself online? Research reveals serious weaknesses…

Published

on

Top password manager products have fundamental flaws that expose the data they are designed to protect, rendering them no more secure than saving passwords in a text file, according to a new study by researchers at Independent Security Evaluators (ISE).

“100 percent of the products that ISE analyzed failed to provide the security to safeguard a user’s passwords as advertised,” says ISE CEO Stephen Bono. “Although password managers provide some utility for storing login/passwords and limit password reuse, these applications are a vulnerable target for the mass collection of this data through malicious hacking campaigns.”

In the new report titled “Under the Hood of Secrets Management,” ISE researchers revealed serious weaknesses with top password managers: 1Password, Dashlane, KeePass and LastPass.  ISE examined the underlying functionality of these products on Windows 10 to understand how users’ secrets are stored even when the password manager is locked. More than 60 million individuals 93,000 businesses worldwide rely on password managers. Click here for a copy of the report.

Password managers are marketed as a solution to eliminate the security risks of storing passwords or secrets for applications and browsers in plain text documents. Having previously examined these and other password managers, ISE researchers expected an improved level of security standards preventing malicious credential extraction. Instead ISE found just the opposite.

MWC: Next generation of inflight connectivity to be unveiled

Published

on

Next week at Mobile World Congress, the Seamless Air Alliance will reveal progress on its mission towards enabling the next generation of inflight connectivity. This follows a significant start for the Alliance, which has seen membership increase five-fold since the first meeting in June of last year. The Alliance has a new research laboratory setup and continues progress through its three working groups, writing specifications for the technology, requirements, and operations.

These developments represent a huge leap towards the goal of making connectivity as easy and enjoyable in the skies as it is on the ground. Appearing as part of the Airbus stand (Hall 6, stand 6G34), the Seamless Air Alliance will reveal specification topics that have been completed and published to its membership.

“The passenger experience with inflight connectivity remains one of the great technology challenges. From Day One we have been determined to deliver on our mission to bring industries and technologies together to make the inflight internet experience simple to access and a delight to use,” said the Alliance’s Chief Executive Officer, Jack Mandala.

“I have been tremendously encouraged by the enthusiastic and committed response we have seen and the widening areas of expertise we can call upon as more and more companies and organisations continue to join us,” he added.

Announced during MWC 2018, the Seamless Air Alliance has since grown to twenty-three membercompanies with more than one-hundred key personnel from across the membership participating in its three working groups, with numbers continuing to increase.

The Seamless Air Alliance was created by founding members Airbus, Airtel, Delta Air Lines, OneWeb and Sprint, and quickly joined by Air France KLM, Aeromexico, and GOL Linhas Aereas Inteligentes and global technology leaders including Astronics, Collins Aerospace, Comtech, Cyient, iDirect, Inmarsat, Intelsat, Latecoere, Nokia, and Panasonic. 

Today, the Alliance is pleased to announce five additional new members: Adaptive Channel, Etihad Airways, GlobalReach Technology, Safran, and SITAONAIR.

“We are extremely pleased to have these companies join and be a part of the companies driving the next generation of connectivity.” said Mr Mandala.

The Seamless Air Alliance will enable travelers boarding any flight, on any airline, anywhere in the world, to use their own devices to automatically connect to the Internet with no complicated login process nor paywall to scramble over.

The Alliance is also announcing the release of a new research study on the economic benefit of standardization on the inflight connectivity market at Mobile World Congress. This report is available for download at https://www.seamlessalliance.com/publications/

The Alliance is moving rapidly towards an expected demonstration of the technology later in 2019 and anticipates massive interest in Barcelona from the whole communications eco-system.
