Existence and prominence of the internet within managed corporate network has become an essential ingredient for enterprise resource planning that many such inter corporate networks thrive on works with always on internet connectivity. Extended networks of corporate are infused due to presence of internet architecture and it becomes successful when such network remains connected and stays secure. Global intelligence comes with various levels of dynamic security which can be accessible from different nodes as well as interconnected and spirals inside out of every part of an organization.
From day to day, internet world has seen the presence of sophisticated malwares which are well-planned to completely hack into cyber network. Most of times prolonged corporate networks aimed to provide sufficient intelligence and speed up entire global operations of organizations. It further reduces risk attached with business houses as centralized work structures are completely abolished and being replaced with decentralized work participations.
This reduces extra pressure on centralized enterprise and delimit and more powers to different units in order to transcend powers to different units. Think of a self hosted site similar to central office of enterprise and when that site is accessed by customers all over the world, then it can be called as clients of such sites, then total loads on central server becomes more than what it is anticipated. So, due to such overload on the server, work pressure on central server becomes more and sometimes not so tolerable due to these constant pressures from the client side.
In a centralized enterprise environment, work pressure from demands of clients increases many times. Now, when that website hires content delivery network and it spreads to different continental zones and stores server there, then pressure on central server reduces drastically. Why, as other servers of content delivery networks stores at different continents static files of website and serves those files to nearest visitors or clients and provide website available readily to users.
In this way, pressure on central server becomes lesser and efficiency of the work comes to become higher. Similarly, in order to reduce completely over dependence on central office there ought to be created smaller subunits which are connected to the central office through high speed internet network.
So, prime importance is to protect such network from external invasions from hackers and immediate invasions from trespassers. Enterprise must assess the impact of advance attacks on its central server and should prepare and create stronger protective boundaries along with its entire internet infrastructure.
Cost of advance attacks:
There have been many instances of such attacks to enterprise networks where most of its security databases wiped out completely which not only present huge losses to the enterprise in terms of monetary but also provide gigantic losses in terms of its brand loyalty and brand values. Sometimes back some anonymous organization hacked into the database of Sony and incurs losses to millions of rupees to them. All these are advance attacks which incur huge costs on enterprises in terms of operations of detecting and forming the team of information technology experts in order to create systematic investigations into forms and manners of attacks into enterprises.
Loss of privacy of clients leads to non-compliance penalties paid by an enterprise which also included in cost of advance attacks. Then, formal calculations on recovering from the database which will need to be done to re-enter entire transactions and it provides optimum level of cost of advance attacks as cost incur on recovery of the database is huge. Advance attacks on transaction database of organization could lead to permanent and consistent damage of brand and reputation. How customers are reacting to this and how their confidence could be revived and how their privacy invasions would not be done again is all these which need to be dealt with stronger and potential decision making could lead to huge expenditure and cost to company.
Advance attacks on enterprises are always carefully planned and most times are executed within live database transactions so that within pulse of seconds the entire database is stolen and host database could be corrupted from remove command. By using real-time command and control hackers, provide lesser time and duration to system administrations to respond and react. Only company with pervasive patching of zero-day vulnerabilities could overcome such humongous attacks. Persistent control and prevention of zero-day vulnerabilities required stronger skilled information technology professionals. Continue persistence in gathering intelligence and continuous learning of different ideas from around different work fields leads to stopping of such menace. It does come with extreme cost.
What it worries most is that most of cyber criminals are well –organized and they come with brighter ideas and are well protected by certain government where the laws of the world are hardly applicable to them. Business of hacking and stealing data from enterprise haves becomes a larger industries where competitive organization hire such cyber criminals to steal these data and gain from other’s competitive advantages. Many a times, there are some hacker activities who hacked into popular enterprises or government’s database to show case their dissent against work order and the way these companies functions. Most of times, such attacks do not come under one single roof and one single day.
Most of times these attacks come upon under the veiled of several DOS attacks to website which many times are completely ignored by the system administration. All these are parts and parcels of warning signals from hackers to test out mentality of system administration in order to begin a larger strike of stealing databases and transactional details. Most of times, continuance persistence DOS attacks as well as larger bot-net attacks could unite becomes the most difficult attack to central-database.
Advance persistent threat:
Main aim of botnet is to hijack the server and create temporary content delivery networks for hackers and prepare the ground to create DOS attacks. Through botnet they can spy on network activities and becomes a shadow system administrator. They can create an even playing field to initiate advance attacks which come in superlative combination of various intrusion techniques. By staying at the stage of botnet, hackers continue to practice and persist on accessing network perimeters of organization. Day by day while staying inside organizational parameters of enterprises they initiate a large amount of attacks with some rare combination of hacking ideas to get rid of the entire data base of organization.
First, they hide their presence in front of other users and slowly gain maximum leverage before initiating all out attacks against transactional database of organizations. These hackers carry on advance persistent threat for a long time inside the server of enterprises anonymously. Though, for every advance persistent thread there are life cycles and hackers persist on working within these parameters to steal databases of enterprise servers.
These botnets attacks are so successful that most times only 30 percentages of such attacks are discoverable by enterprises only and the rest is discoverable by third party institutions. This goes on to show and prove that most of times, most of enterprises hardly implement stricter security and this goes on to show the abysmal level of state of security of databases of enterprises which needs to be well guarded and secured in order to have a secure enterprise management system. Proliferation of enterprise network channels through mobile mediums have grown in astronomical limits which lead to more risked posing by such application and devices.
Now, there are numerous ways a database could be accessed as well as there are innumerable ways in which such methodology could risk extreme risk to organizations. Due to advent of bring your own device and installation of server access in those devices of employees organization face huger and higher risk of vulnerability of attacks due to opening of large number of nodes all around and it poses greater level of risks to centralized database of organization. More and more applications are connected to a central database server with the implementation and initiation of different proxy servers which provides non-stop entrances to clients to a central server.
With these come the option of bringing your own device; hackers could intrude into increasing backdoor corporate assets that could steal entire database of organization. Mobile applications are available free of cost and most of these applications could run into store house of malwares which could vitiate the entire enterprise atmosphere. Most of these applications are available in the form of bundled apk files which could harness provision for malwares and that could have deterred the possible stable attendance of database.
With so many wide arrays of applications, conversations and mode of clients to join into corporate networks, it rests little chance for system administrators to find out from where such malwares comes and how to stop such malwares from intruding into system resources is of highest point of concern for all security experts.
Network behavior analysis:
If you cannot see the root position of hackers then you cannot secure it. One need to understand the process of reverse re engineering in order to detect the pervasive instances of advance attacks and successfully mitigate advance attacks by observing intrusion prevention techniques. That is why most of security specialists’ advocates of creating security based upon behavioral analysis of entire system architecture. If there happens to be at one such time, any abnormality in function of system, then other left over processes ought to stay within those parameters of system and thus the identity of hacker could be known at the earliest point of time due to complete behavioral analysis of entire system architecture.
Problem with this kind of analysis stay with complete network behavioral analysis through deployed enterprise anti malware system with a proper establishment of security information and event management tools to dissect trespassers and hackers through the entire system level administration. Though, all these behavioral functions lead to huge investment in architecture as well as investing heavily on in-house security experts’ team to put forward a stringent security system that would recognize multiple fingerprints of larger traffics to stop malwares from intruding into the enterprise system.
