It may be a good idea to run a speed test both before and after tweaking!
Most basic tweaks are covered by using our broadband tweaking tool, the SG TCP Optimizer (simply choose your maximum advertised internet speed and apply the optimal settings).

PLEASE TRY TO ANSWER THESE QUESTIONS IF YOU NEED HELP

The answers to the following questions are important when asking for assistance in tweaking your connection, you must help us help you!
The more information you provide, the more informed decisions we can make to help.

1. What is your advertised internet speed ? i.e. 12Mbps/768kbps (12 Megabits/second downstream, 768 kilobits/second upstream)
2. What actual transfer speed do you get? (you can try a speed test from speedguide.net or speedtest.net)
3. Who is your Internet Provider (ISP), and what type of connection do you have ? i.e. Comcast Cable, AT&T PPPoE DSL, ISDN, 56K, etc.
4. What are your current settings ? do a TCP/IP Analyzer test and copy/paste the results in your post.
5. Your modem/router/ap brand ? (i.e. Motorola SB6100 cable modem, Linksys WRT54GS Wi-Fi router, etc.)
6. Your Operating System ? (i.e. XP,Vista 64bit,Windows 7, etc.)

You can also provide additional information to help us understand your issues, i.e. latency, gaming, transfer speed, browsing problems, etc. Please start your own thread.



Additional Notes

Your goal should be to get to ~90% of your advertised speed. The rest may depend on factors beyond your control, such as protocol overhead, routers, servers, line quality, congested nodes, etc. Tweaking only optimizes your end of the connection, and even though it is usually the bottleneck, your connection is still dependent on the quality of the feed that your ISP provides.

Separate your Cable/DSL modem and router/access point - don't stack them! Many devices are not adequately shielded and very succeptible to EMI (electromagnetic interference) so they should be placed at least 1-2 feet apart from each other and other possible sources of EMI (power supplies, fluorescent lighting, cordless phones, etc.)

MTU value should be set properly first, before other tweaking: 56K/PPPoA DSL/Cable Modem - 1500, PPPoE DSL - 1492 or 1480

Connect your modem via ethernet (Network Interface Card) instead of USB, if possible. Ethernet is faster and much more stable. Using the latest drivers from your NIC's manufacturer can also help, they often have advanced settings that help further optimize the performance of your NIC.

Minimize the number of protocols - in your NIc's properties (general tab), uninstall all protocols you do not need. Theoretically, you only need "Internet Protocol TCP/IP" version 4 for a stand-alone PC. You can disable NetBios over TCP/IP if you do not use file and printer sharing.

SQL injection is simple technique to maliciously attack in web application that is use supplied data from client embedded as SQL statements. And attacker must be used access client database by using command line. SQL injection method different but they are all hacker used single vulnerability in the web application.
There are available attack it’s maintain top 10 list of famous attack they are likely used hacker. This type attack as well as same of crosses site scripting (XSS) attack, mostly user risk of the part web application security just because this type hacker attack directly on the database management system if any hacker attack the database so who is guess easily access data.
While web application provide more facilitate for secure this type hacking attack. But most of hacker while attack include some file like that they are used XSS cross site scripting, SQL Injection, Header Injection, Log Injection.
Hacker attack to the user database so that used code programs and every attacking program make them bogeyman. They are common and very successful attack to the internet.
