SMEs are a sector where it is difficult for technological innovations to take root, with companies mostly opting for conservative criteria of amortizing investments in existing systems, i.e., they tend to update what is installed rather than undertake a comprehensive renewal.
In a society that is ever increasing its use of technology and showing no signs of slowing down, it is becoming more and more pertinent to ensure the best quality products. Companies are being pushed to reach a wider audience by accelerating innovation and constantly improve its customers´choice within their platform. Striving to advance the development process while perfecting the overall quality and security of software is top priority.
Carriers today are faced with spiraling changes in the WAN market. For varying reasons, it’s a market that takes an individualized approach to each type of customer. From the residential sector to large corporations, the number of access circuits to the Internet make up a huge part of the telecommunication carriers’ business in Spain. Having said this, what progress is being made in the business? How can the carriers meet the demands and needs present in the market?
Nowdays many organizations increasingly look forward to using Cloud technologies and allocating their services on the Cloud. This is not only what global companies or IT companies are working on, this is what any companies are moving towards, if they are looking for a modern and suitable technical solution for their day to day transactions.
Why has visualization of applications over network become such a critical point?Firstly, the move of IT infrastructure to the cloud means our current understanding of level 3 network traffic (IP) is insufficient to characterize applications transmitting over said network: Application servers had fixed, known IP addresses in traditional data centers, whereas IP addressing in cloud is no longer controlled by the organization using these services.
Secondly, far more applications (both corporate and personal) are in circulation today than a few years ago. Said applications have not, in general, been designed with bandwidth optimization in mind and all have different needs and behaviors. This means some applications can (and do) adversely affect others if the network is incapable of applying different policies to prevent this.
The vast majority of applications use http and https for communication mainly to evade, or minimize, possible negative effects arising from security policies or IP addressing (NAT) over the network. This means the transport layer (TCP or UDP port) is unable to adequately identify network applications as they tend to use the same ports (http 80 and https 443).
To further aggravate the problem, companies must provide connectivity to an enormous array of ‘authorized’ local devices. Remote local networks today, unlike the traditional single terminal of yesterday, are more varied and far less controlled: Wireless offices, guest access, home access, BYOD, IoT etc. Consequently, the difficulties in analyzing traffic, caching systems and CND also escalate
Finally this greater diversity increases security risks: viruses, malware, bots, etc. These, in turn, tend to generate “uncontrolled” network traffic that needs to be detected and characterized. At this point, the close link between visibility and security at the network level raises its head (with all its repercussions and analysis), a subject that we’ll tackle another day.
The above points make it very clear that analyzing network traffic has become more and more intricate over the last few years, boosting the need for new tools with greater capacity. Otherwise, we simply won’t know what is going through our network, placing it not only at risk but unnecessarily increasing its upkeep. Given the tremendous amount of information handled, using tools that are able to intelligently filter the information received and provide high level of granularity in analysis and reports is absolutely essential. It’s here where big data analysis technologies bring huge advantages when compared to traditional tools.
Well aware of this recent difficulty, users need application visibility and control solutions to meet these new needs.
As part of its access routers and management tool, Colibri Netmanager, Teldat offers visibility and control solutions for network applications capable of meeting the aforementioned market needs.
