The move after the undertaking administrator will include one of the accompanying two stages. Either get a degree on the board or stick around in your profile for a significant number of years. Anything higher is only here and there specialized, and organizations usually anticipate that you should increase a touch of administrative information either through a degree or work understanding. On the off chance that the head honchos are happy with your exhibition, positions like CTO are rarely far, yet you will be confined to the IT business as it were. Being an MCA that ought not to act like an issue by any stretch of the imagination. That is the stature you can arrive at following the effectively accessible alternatives. Be on an organization’s board and deal with a whole division.

Scope in future jobs

Studying Computer Applications, you may realize that the present period likewise has occupations that are yet to come to success. Some profiles will come up and soon accumulate a lot of demand. The outright option choice in the field of Internet of Things (IoT) where you can join any up and coming organization as an internetworking official or systems administration official and gradually progress onward to the region of IoT. The equivalent can be said about positions like programming improvement, equipment innovation, or application programming advancement. You will be qualified for all in the wake of completing the course and, afterward, working your way into the roads of artificial intelligence, blockchain, machine learning, and so on.

Furthermore, the blast of computer-generated reality is as of nowhere. This profile requires gifted software engineers. And afterward, there are the fields of automated vehicles, drone innovation, cybersecurity, and others. The whole specialized world is again observing a move and a new interest for computer experts are coming on the off chance that you can structure your MCA to fit these. Select the correct educational plan, and afterward, a vocation after, you can work in these up and coming fields that will see more significant salary scales inferable from their vast interest.

Definition Of A Survivable Computer System

A computer system, which may be made up of multiple individual systems and components, designed to provide mission critical services must be able to perform in a consistent and timely manner under various operating conditions. It must be able to meet its goals and objectives whether it is in a state of normal operation or under some sort of stress or in a hostile environment. A discussion on survivable computer systems can be a very complex and far reaching one. However, in this article we will touch on just a few of the basics.

Computer Security And Survivable Computer Systems

Survivable computer systems and computer security are in many ways related but at a low-level very much different. For instance, the hardening of a particular system to be resistant against intelligent attacks may be a component of a survivable computer system. It does not address the ability of a computer system to fulfill its purpose when it is impacted by an event such as a deliberate attack, natural disaster or accident, or general failure. A survivable computer system must be able to adapt, perform its primary critical functions even if in a hostile environment, even if various components of the computer system are incapacitated. In some cases, even if the entire “primary” system has been destroyed.

As an example; a system designed to provide real-time critical information regarding analysis of specialized medications ceases to function for a few hours because of wide spread loss of communication. However, it maintains the validity of the data when communication is restored and systems come back online. This computer system could be considered to have survived under conditions outside of its control.

On the other hand, the same system fails to provide continuous access to information under normal circumstances or operating environment, because of a localized failure, may not be judged to have fulfilled its purpose or met its objective.

Fault Tolerant And Highly Availability Computer Systems

Many computer systems are designed with fault tolerant components so they continue to operate when key portions of the system fail. For instance; multiple power supplies, redundant disk drives or arrays, even multiple processors and system boards that can continue to function even if its peer component is destroyed or fails. The probability of all components designed to be redundant failing at one time may be quite low. However, a malicious entity that knows how the redundant components are configured may be able to engineer critical failures across the board rendering the fault tolerant components ineffective.

High availability also plays a role in a survivable computer system. However this design component may not maintain computer system survivability during certain events such as various forms of malicious attack . An example of this might be a critical web service that has been duplicated, say across multiple machines, to allow continuous functionality if one or more the individual web servers was to fail. The problem is that many implementations of high availability use the same components and methodology on all of the individual systems. If an intelligent attack or malicious event takes place and is directed at a specific set of vulnerabilities on one of the individual systems, it is reasonable to assume the remaining computer systems that participate in the highly available implementation are also susceptible to the same or similar vulnerabilities. A certain degree of variance must be achieved in how all systems participate in the highly available implementation.

What’s The Difference Between An Attack, Failure, And Accident? How Do These Differences Impact A Survivable Computer System

In many cases when I am discussing the security of systems with customers, the question of business continuity and disaster recovery come up. Most companies that provide a service that they deem critical just know the system needs to be operational in a consistent manner. However, there is typically little discussion about the various events or scenarios surrounding this and that can lead to great disappointment in the future when what the customer thought was a “survivable computer system” does not meet their expectations. Some of the items I like to bring up during these conversations is what their computer systems goal and objective is, what specifically does continuous operation mean to them, and specifically what constitutes an attack, failure, or accident that can cause loss of operation or failure to meet objectives.

A failure may be defined as a localized event that impacts the operation of a system and its ability to deliver services or meet its objectives. An example might be the failure of one or more critical or non-critical functions that effect the performance or overall operation of the system. Say, the failure of a module of code that causes a cascading event that prevents redundant modules from performing properly. Or, a localize hardware failure that incapacitates the computer system.

An accident is typically an event that is outside the control of the system and administrators of a local / private system. An example of this would be natural disasters such as hurricanes, if you live in south Florida like I do, or floods, or wide spread loss of power because the utility provider cut the wrong power lines during an upgrade to the grid. About two years ago, a client of mine who provides web based document management services could not deliver revenue generating services to their customers because a telecommunications engineer cut through a major phone trunk six blocks away from their office. They lost phone and data services for nearly a week.

An now we come to “attack”. We all know accidents will happen, we know that everything fails at one time or another, and typically we can speculate on how these things will happen. An attack, executed by an intelligent, experienced individual or group can be very hard to predict. There are many well known and documented forms of attacks. The problem is intelligence and human imagination continuously advance the form of malicious attacks and can seriously threaten even the most advanced designed survivable computer systems. An accident or failure does not have the ability to think out of the box or realize that a highly available design is flawed because all participants use the same design. The probability that an attack might occur, and succeed may be quite low, but the impact may be devastating.

Conclusion

One of the reasons I wrote this article was to illustrate that it’s not all about prevention. Although prevention is a big part of survivable computer system design, a critical computer system must be able to meet its objectives even when operating under hostile or stressful circumstances. Or if the steps taking for prevention ultimately prove inadequate. It may be impossible to think of all the various events that can impact a critical computer system but it is possible to reasonably define the possibilities.

The subject of survivable computer systems is actually one of complexity and ever evolving technology. This article has only touched on a few of the basic aspects of computer system survivability. I intend on continuing this article to delve deeper into the subject of survivable computer systems.

In the new computer age, We don’t always log on from home where our PC’s are thoroughly protected. (You took care of that already, right?) Cyber cafes, libraries, airports, hotels and other places offer use of a public terminal for those on the go. But, unfortunately, those computers may not always get secured well nor checked regularly. And, since others use them, they can get infected only minutes before it’s your turn.

Here are a few tips for how to protect your information while using a public computer.

Most of the email clients nowadays allow you to forward email from one account to another, just as you forward your phone calls. Take advantage of this feature to enhance your security.

If you plan to be away from home for a few days – but aren’t using your regular computer or laptop – try to forward your email to an account you set up especially for the trip. This helps protect your information a lot.

Both the account and the password are much less likely to be known to scam artists. Yet, you can retrieve any email sent while you’re away from your regular PC. Also, if the userid and password do get cracked, your ongoing risk is low, since you’ll be abandoning this temporary account shortly.

If you have to log in to a public computer with one of your regular username change the password the first time you use it away from home. Then change it back when you get back home, This limits your exposure time.

Public computers can contain a specific kind of spyware/trojan called ‘a key-logger’ that records your every keystroke. Apart from getting your logins and passwords, that also allows the thief to access anything else you typed in during your session. So, you must avoid making credit-card transactions online or accessing your online banking and credit-card accounts.

Before you go to any site that would require a username and/or password, disable any auto-complete or password storing feature. If you can because some public computers have these features locked down by the administrator.

Avoid unfamiliar sites, if practical, while you are away. Most online hacks come from auto-downloads of spyware, viruses, etc. Few of the sites you visit regularly are likely to have those. Just as you would avoid talking to unsavory strangers while on a trip, avoid dicey websites.

Defer clicking on ads while you’re away from home. Those can lead to just the kinds of sites mentioned above.

Once you are done using the public computer, erase – if you can – here again administrators may not allow you to access the feature – any Temporary Internet files, cookies, etc. This helps protect not only you, but leaves the computer in a better state for the next user.

Needless to say, don’t leave any downloaded files on the computer and never allow anyone to look over your shoulder while you are typing in a password or other sensitive information.

Paranoia isn’t needed. But a little awareness and sound judgment while using a public computer will help keep your information secure – then and after you get back home.

One last tip would be to use a better secure browser like Firefox or Opera while surfing on your home PC as well as a public computer.

If you ve just started to work with lightweight access points, you might have already come across the term rogue access point .

The questions most people ask are:

What is it?

What can I do about it?

Rogue access points are determined by your lightweight wireless LAN controller as an access point it does not control. This can mean that there is an AP on your site that should not be there however in some cases it may be an access point which is used for a hotspot, such as a nearby coffee shop.

The good news is that on your controller you can set up some rules. These rules are used to automate the process of determining if a rogue access point is an issue or not.

You can classify on a number of different parameters and classifying on signal strength or the SSID broadcast allows you to determine if the AP may be is a friendly or a malicious AP.

If, for example, the rogue AP has the same SSID you have, then the chances are that it s malicious. It s flagged as such and you can investigate. Rogue APs are an issue because a hacker may set up an access point to impersonate one of your APs. They may also be used to send out disconnect messages, so you should also configure your network to allow clients and APs to authenticate each other.

Generally when you switch a new lightweight network on, you ll find that there are sometimes dozens of rogue APs identified however using the automated rules allows you to determine which may be safely ignored.

If you determine a rogue AP is malicious, you have several options (depending on your network configuration):

You can perform a wired trace to determine if the AP is connected to your wired network and you can then disable the switchport where the rogue AP is connected.

You can use location tracking to determine the likely location of the rogue AP and physically visit the location.

You can contain the rogue AP. This option will cause nearby APs from your wireless LAN to send de-authenticate and disassociate messages to any clients trying to associate to this rogue AP effectively rendering the rogue AP useless when in the presence of your wireless LAN. This option can be activated manually on a per AP basis or a rule can be setup to deactivate all APs connected to your wireless LAN (This option must be used with caution as accidentally disabling somebody else s wireless LAN outside of your premises may have legal ramifications)

Rogue access points are a fact of life any time you stand up a managed lightweight network you re going to see them the question is how you manage which are a threat to your business and which ones you don t care about. Once a new network is deployed it can take a fair bit of upfront work to categorise all the rogue APs.

The real lesson is that a wireless network isn t a static thing it changes and requires ongoing support and maintenance.
