🦑🐧 How to properly protect sysctl on Linux from spoofing and Syn flooding

1) The sysctl system also helps prevent attacks such as SYN floods and IP spoofing.

It also logs some types of suspect packets - spoofed packets, source routed packets, and forwarded packets.

2) You can change kernel parameters at run time using the sysctl command, or you can make changes to the system configuration file to make these changes more permanent.

3) I want to show you how you can protect sysctl by quickly editing the config file.

This configuration will be as follows:
Disable IP forwarding
Disable packet forwarding
Disable accepting ICMP redirects
Enable protection against incorrect error messages
What you need:

4) Linux
User with sudo privileges
Note: I will be demonstrating an example on Ubuntu Server 18.04, but the process is the same for most Linux distributions.
How to edit sysctl config file
Log into your Linux server or desktop and open a terminal window.

5) In the terminal, enter the command:
sudo nano /etc/sysctl.conf
First required parameter:
# net.ipv4.ip_forward = 1
change to:

net.ipv4.ip_forward = 0
Next line:

# net.ipv4.conf.all.send_redirects = 0
change to:

net.ipv4.conf.all.send_redirects = 0
Find the line:

# net.ipv4.conf.all.accept_redirects = 0
change to:

net.ipv4.conf.all.accept_redirects = 0
Add the following line below that:

net.ipv4.conf.default.accept_redirects = 0
Finally, add the following lines to the end of the file:

net.ipv4.icmp_ignore_bogus_error_responses = 1
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_max_syn_backlog = 2048
net.ipv4.tcp_synack_retries = 3
net.ipv4.netfilter.ip_conntrack_tcp_timeout_syn_recv = 45

6) The above settings do the following:

Includes protection against incorrect error messages
Enable SYN cookies to prevent the server from dropping connections when the SYN queue is full
Increase SYS queue size to 2048
W akryvayut state SYN_RECV compound pre
Decrease SYN_RECV timeout value to help mitigate SYN flood attack

🦑TYPES OF FIREWALLS :

1) Firewall Types:
Firewall Package Filtering:
This firewall form tracks TCP packet headers at the level of TCP, and searches for source address, target address, source port, destination port, and protocol. They authorize or disallow packets in compliance with written laws, depending on these information.

Any 80 Allow – this rule tells the firewall to permit any packet from any source to port 80 from any source.

2) Firewall Circuit Level:

The session levels are operated and the links are filtered. They are searching for trustworthy connections and filter dependent on trusted connections right before the packets are transferred.

3) Firewalls application:

Alternatively they are called the Proxy firewall; operate on the server layer, filtering packets of the application level. There are various rules for filtering the data at the proxy. Web servers normally accessed by internet users can be positioned as proxy servers outside the internal network and all connections to the proxy can therefore be directed; the internal network can then be shielded from external links.


4) Firewall state-of-the-art:

This is the firewalls mix. It functions on the Network Layer, filters transport speeds, connections at the session level and applications data. This has a state table with separate links status and a law table. It has a state table. It also tracks the number of sequences to deter related attacks.
