The Browser Object Model (BOM) in JavaScript includes the properties and methods for JavaScript to interact with the web browser.
BOM provides you with window object, for example, to show the width and height of the window. It also includes the window.screen object to show the width and height of the screen.

In JavaScript, almost "everything" is an object.
-Booleans can be objects (if defined with the new keyword)
-Numbers can be objects (if defined with the new keyword)
-Strings can be objects (if defined with the new keyword)
-Dates are always objects
-Maths are always objects
-Regular expressions are always objects
-Arrays are always objects
-Functions are always objects
-Objects are always objects
Loops execute a block of code a specified number of times, or while a specified condition is true.
Often when you write code, you want the same block of code to run over and over again in a row. Instead of adding several almost equal lines in a script we can use loops to perform a task like this.
In PHP, we have the following looping statements:
while - loops through a block of code while a specified condition is true
do...while - loops through a block of code once, and then repeats the loop as long as a specified condition is true
for - loops through a block of code a specified number of times
foreach - loops through a block of code for each element in an array
Session and cookies knowledge is very important for a web developer. In these slides we are going to explore basics of Sessions and Cookies in PHP. How to create and destroy a session. How to create and destroy a cookie. How sessions and cookies are stored.

Working with files in PHP can be a fun and a frustrating task; one you never know when you'll be asked to do. In our first beginner PHP talk, we'll go over how to work with files and some of the most common built in functions to help accomplish your tasks.
It Covers subject 15CS71-Web Technology and Its Applications, Module-5, from B.E. Computer Science & Engineering- Semester–VII, under Visvesvaraya Technological University, Belagavi
In the following slide I am going to demonstrate the difference between Cookies and Session and how to use each and why. Also, I am going to talk a bit about session hijacking
There are seven levels of cache between your code and the users browser experience. You can take advantage of them all to provide a quicker, slicker, better user experience for the user and it won't cost you a dime to do it. You can use an OpCode Cache on the Server, a Content Development Network (for free), make use of the browser cache, setup an App Cache, use Session and Local Storage. They are all there, they are all free and this talk will go over all of them, the pros and the few downsides.
In this session, you will learn about what are sessions, cookies, how we can implement authentication in nodejs. And will also see about the CSRF attacks.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
3. So…So…
Cookies Sessions
Limited storage space Practically unlimited
space
Insecure storage client-
side
Reasonably securely
stored server-side
User controlled No user control
4. How do ‘Sessions’ work?How do ‘Sessions’ work?
• They are based on assigning each user a unique
number, or session id. Even for extremely heavy use
sites, this number can for all practical purposes can
be regarded as unique.
e.g.
26fe536a534d3c7cde4297abb45e275a
5. How do ‘Sessions’ work?How do ‘Sessions’ work?
• This session id is stored in a cookie, or passed in the
URL between pages while the user browses.
• The data to be stored (e.g. name, log-in state, etc.)
is stored securely server-side in a PHP superglobal,
and referenced using the session id.
7. Starting or Resuming aStarting or Resuming a
SessionSession
session_start();
PHP does all the work: It looks for a valid session id in
the $_COOKIE or $_GET superglobals – if found it
initializes the data. If none found, a new session id is
created. Note that like setcookie(), this function
must be called before any echoed output to
browser.
8. Starting or Resuming aStarting or Resuming a
SessionSession
session_start();
When doing anything with sessions, this is always
called first!
9. Storing Session DataStoring Session Data
• The $_SESSION superglobal array can be used to
store any session data.
e.g.
$_SESSION[‘name’] = $name;
$_SESSION[‘age’] = $age;
10. Reading Session DataReading Session Data
• Data is simply read back from the $_SESSION
superglobal array.
e.g.
$name = $_SESSION[‘name’];
$age = $_SESSION[‘age’];
11. Session PropagationSession Propagation
• Sessions need to pass the session id between pages
as a user browses to track the session.
• It can do this in two ways:
o Cookie propagation
o URL propagation
12. Cookie PropagationCookie Propagation
• A cookie is stored on the users PC
containing the session id.
• It is read in whenever session_start(); is
called to initialize the session.
• Default behaviour is a cookie that expires
when the browser is closed. Cookie
properties can be modified with
session_set_cookie_params if required.
13. URL PropagationURL Propagation
• The session id is propagated in the URL
(…some_folder/index.php?sid=26fe536a534d3c7cde4297abb45e275a)
• PHP provides a global constant to append the
session id to any internal links, SID.
e.g.
<a href="nextpage.php?<?=SID?>">Next page</a>
14. Which one..?Which one..?
• The default setup of a PHP server is to use both
methods.
o it checks whether the user has cookies enabled.
o If cookies are on, PHP uses cookie propagation. If cookies are off it uses
URL propagation.
15. And this means..?And this means..?
• That as developers, we must be aware that sessions
can be propagated through URL, and append the
constant SID to any internal links.
• If sessions are being propagated by cookies, the
constant SID is an empty string, so the session id is
not passed twice.
16. Destroying a SessionDestroying a Session
Often not required, but if we want to destroy a
session:
// clear all session variables
$_SESSION = array();
// delete the session cookie if there is one
if (isset($_COOKIE[session_name()])) {
setcookie(session_name(),'',time()-42000,'/');
}
// destroy session
session_destroy();
// avoid reusing the SID by redirecting
// back to the same page to regenerate session
header('Location: '.$_SERVER['PHP_SELF']);
17. Session ExpirySession Expiry
• By default, PHP sessions expire:
o after a certain length of inactivity (default 1440s),
the PHP garbage collection processes deletes
session variables. Important as most sessions will
not be explicitly destroyed.
o if propagated by cookies, default is to set a
cookie that is destroyed when the browser is
closed.
o If URL propagated, session id is lost as soon as
navigate away from the site.
18. Long-term SessionsLong-term Sessions
• Although it is possible to customize sessions so that
they are maintained after the browser is closed, for
most practical purposes PHP sessions can be
regarded as short-term.
• Long-term session data (e.g. ‘remember me’ boxes)
is usually maintained by explicitly setting and
retrieving cookie data.
19. Session Hi-jackingSession Hi-jacking
• A security issue: if a malicious user manages to
get hold of an active session id that is not their
own..
e.g.
o user 1 browsing site with cookies disabled (URL
propagation).
o user 1 logs in.
o user 1 sends an interesting link to user 2 by email.. The
URL copy and pasted contains his session id.
o user 2 looks at the link before session id is destroyed,
and ‘hijacks’ user 1’s session.
o user 2 is now logged in as user 1!!
20. …… rule of thumb …rule of thumb …
If you are truly security conscious you should assume
that a session propagated by URL may be
compromised. Propagation using cookies is more
secure, but still not foolproof..
