Introduction

Structured Query Language (SQL) injection is a code injection technique used in requesting, deleting and updating information from databases. Therefore, it is one of the main web attack mechanism used by hackers to steal data. This attack allows the hacker to inject SQL commands into allowing them access data in a database, as it takes advantage of improper coding in the web applications. This kind of attack bypasses firewalls and endpoint defenses, because web based forms must allow access to databases so as to give some sort of response.

Impacts of SQL

SQL injections pose a serious threats to database servers in computer networks. With ...

Indeed, several problems have been experienced even by the most advanced companies regarding interoperability issues, continuously increasing maintenance cost which was not predicted beforehand, and the ever present security issues. A number of possible solutions have been tested and implemented by these companies. CISCO particularly came up with the following possible options to eliminate interoperability issues in networks: usage of same radios or communication systems, the use of gateway devices, and the usage of IP networks for radio interoperability. (Cisco.com) Usually, the increasing maintenance cost in networks are unforeseen as these “required” maintenance were not predicted during the proposal ...

Security process

Security itself is not a technology rather it is a process that has to be applied (Wadlow, 2000). This is because new threats are developed every day, which require new forms of protection (Nordquist, 2002). The security process involves the analysis of a problem followed by the development of a solution based on the analysis and then evaluating the solution.
- Analysis
- This involves learning all concepts that concern the nature of the threat attack.
- Synthesis

A small business may implement firewall in order to protect individual PCs on the network. Firewalls are available as either software or hardware components. Software firewalls are installed on each computer, but this choice may be expensive for a small business since it requires regular updating and maintenance.
Hardware based firewalls protect all computers on the network and does not require individual administration on each PC. Rather integration of the hardware firewalls with software controls provides comprehensive security that may include VPN support, antispam, antivirus, content filtering and antispyware (Linda Null).A firewall provides a number of security measures for a ...

Online presence and connection has become more prevalent in the last few years, something that can be highly attributed to the cheaper browsing charges and improved infrastructure. However, this has brought about more danger to the users than earlier especially with the huge risk of spyware and viruses finding their way into an individual’s computer. This has been greatly combated by using firewalls to ensure that a computer is highly protected. A firewall comes in the form of either a hardware device or a mere software application that repels any traffic that the user has not requested (Levine & Young 2012). This ...

Firewall decisions To decide whether the CIO has suggested an effective solution to limit risk of hacking attacks and decrease losses it is necessary to estimate the financial outcomes for two potential developments. The first alternative is inaction of the company with no changes in security system and the second is implementation of firewalls. If the company will not change its risk management strategy it will almost permanently loose 250000$ per year. The total cost of firewalls for 3 years is the sum of 10 firewalls cost and their annual maintenance costs. It equals 125000$. Consequently the cost of ...

DoS and DDoS attacks A Denial-of-Service (DoS) attack is an attack intended to close down a computer or network by making it unreachable to its intentional users. These attacks have achieved by spilling over the aimed computer or network with traffic, or with distribution of information that activates a crash. In both cases, the DoS attack restricts legitimate users to use the service and computer. There are two common ways of DoS attacks that are flooding services and crashing services. Flooding means, the system receives excessive amount of traffic for the server to buffer that cause system to slow down and ...

Supervisory Control and Data Acquisition systems (SCADA) are a subset of Industrial Control Systems (ICS), and they are used to automate the control and monitoring of processes and sets of processes. Such processes include industrial production lines, power grids, rail switching and other critical infrastructure. Traditionally, these systems were isolated and thus secure from cyber-attacks. However, modernization has led to increased complexity, interconnectivity, and digitization. In this regard, today's SCADA systems need to communicate and transfer data from one site to another via communication networks that are at times public e.g. The internet. This development has created security vulnerabilities for ...
